There's a world of difference between SQL and NoSQL, though in both cases, the back-end can hide the implementation details, which has its pros and cons. Pros: You usually don't have to think about it. Cons: When you do have to think about it (optimization, digging into the data to figure out how to model a particular bug) it can be a real PITA if you don't know it well.
Be careful of why startups tend to use the MEAN stack. The two most common reasons I've found is:
- They don't have any money to invest in proper tooling, so they go open source (which isn't bad, per se, but...)
- As I've encountered all too often among hackers that just want to start coding their new cool idea, "let's use NoSQL!" followed by a group mind-fart: "oooh, yeah, cool tech I've been wanting to use."
More generally, yes, learning the nuances of thinking functionally vs. imperatively is definitely a worthwhile exercise, as is learning more than one web stack, if you have good reason too.

As a rule, knowing more stacks allows you to choose the appropriate technology for each project (e.g. the requirements for Amazon's web site differ from those for your local church). The catch here is that you must know the technologies well enough to be able to determine when each is appropriate. This comes mostly from experience.
By analogy from the physical world, a good carpenter should know when to use carpenter's glue, nails, screws, or other fasteners. Each has their place, and it is a poor craftsman who believes that only one type of fastener answers all problems.
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.

Or rather, a good carpenter should know how wire a new plug onto any of his power tools, and maybe do very simple mechanical repairs to them.

What, you mean that all those other things you mentioned can be used as stand-ins for nails?

No, I mean that different types of fasteners are used in different circumstances.

Really? Golly.
Given that that's precisely what you said, I'd never have guessed that it was what you meant.

Never heard of the term MEAN before, but often come across, and am currently using that exact stack to tutor myself on nodejs hosted web sites. All the resources I've found use Mongo, but I feel Mongo is just not right for tabular data, and will eventually substitute PostgreSQL. Overall, I think it's a good stack though.

Have you found any solution to debugging in MEAN? I'm struggling hard on this right now. It seems to be hell/non-existent compared with ASP.NET.

Well, for Angular, the Chrome console is magic, and there are extensions for viewing Angular entities, and for nodejs, there is Node Tools for Visual Studio. I haven't played with it much, but it looks promising. With node, you don't need a web page or browser, you can write some JS functions and debug them straight in VS. I only started my first project with Express last night, but I think there, the node tools will allow you server side debugging, e.g. a breakpoint when a request is received. I'm also very optimistic that Google can integrate Chrome with nodejs, just as MS allows you to debug JSD running in Edge on breakpoints set in VS.

If you anticipate using some of the underlying technologies within the MEAN stack, then there is obviously a benefit to be had from learning all and / or part of it. I've looked at at parts of it previously, in particular Node.js but have never had a reason to explore any further.
If you want to learn something new and feel there is value to be gained from doing so, then go for it.

I don't have an opinion on MEAN; however, you should learn technologies other than C#/ASP.NET.
Every single technology that is mainstream at the time someone enters the IT field will fall by the wayside during their career. I can't think of any technology that was hot when I graduated college that is still mainstream. Many no longer exist in any real sense. Yeah, some are still in use, but it's legacy code.
The IT world will migrate to newer, different technologies. Those that don't migrate get stuck in a backwater niche. I've known far too many people who clung to an old technology because they knew it well, and ended up unemployed while they frantically tooled up on newer technology.
MEAN sounds like a good choice -- it's totally different from C#/ASP.NET and you can learn it OTJ and get practical experience with it. If you never use it again? You've learned another way of thinking, and that is critical to each technology. You will carry the knowledge with you for the remainder of your career.
It is very true that the more we know, the easier it is to learn new things.

How to prepare a tofu:
Step1: Throw it in the trash
Step2: Grill some real meat
Done.

Wrong. Don't waste food, not even that stuff.
0) You need two X chromosomes to happily eat that stuff, so invite some over to get rid of it.
1) If it's not enough, lay out additional breadcrumbs.
2) Now get some real meat.

Tofu is not bad, but you should not expect "meat". It's not, and should stop pretending it is. It soaks up other tastes well, so it's best baked with bacon. Still not meat, but now you have bacon-tasting bean-blocks.
..but I'll prefer a block of tofu (even raw) everyday over that modern insect-meat. Bugger me, something bugs me 'bout those burgers

But I like real food. Real meat rocks! 
..and oh.. can you just leave the bacon out of tofu?

Well, yes, that's evolution. If you were created to eat plant-material you would have had as many stomachs as a cow. Would also mean that your brain would need to be somewhat smaller.

No, otherwise it will taste like tofu

A cow with horns is called a bull, isn't it? And they take craps.

Step 1: Don't let the whole world know you're a "real man"(?) because you eat meat and somehow that's supposed to make you really awesome and manly.
Step 2: Eat whatever the hell you like and don't bother other people with it.
This "I eat meat" stuff was pretty funny at first, but it's getting really old.
Like you never eat a salad or really could not eat anything other than meat.
I've been a vegetarian for almost 2/3rds of my life, but you don't see me posting about salads and being a rabbit
To the people that hate on vegetarians because "they always tell you they're vegetarian": it's because if we don't tell you you'll give us meat and we don't eat that so things will get really awkward... And we won't have food.
Sorry man, nothing personal.
You just posted the wrong thing at the wrong time (the time I read such a post for the 1000th time)

Is that how you view to become a cool guy, awesome and manly? Real man doesn't react like that.
My apology if it bothers you and sorry if it this joke is old for you. FYI, this post has nothing to do if you were a vegetarian or not. Does not mean i prefer meat I don't eat veggies at all. I eat any kinds of veggies alot.
-peace out!
