help to select a right software model
As with any decision, you should approach it like this:
- list the pros and cons of every possible choice.
- link them to the specific scenario.
- select the best* choice.
 
Splitting the first and second steps like that is an approximation that you can't always afford. Sometimes they should be merged to the step:
- predict the real positive and negative effects of every choice.
That step can usually only be approximated, because it usually involves an element of random chance, but usually it can be approximated very well using experience (of yourself and others), detailed information of the complete scenario (not enough given in this question) and logic.
 
* "best" means that the sum of weighted pros plus the sum of weighted cons (cons are negative, so you just add them, not subtract them) is highest over all choices. Don't divide - you're not looking for the "most efficient way to produce 'pro' ", you would often end up making a choice that has no cons (and therefore an infinite efficiency) but those choices usually give very little 'pro'.
 
Usually there are several best choices, that only differ in some trade-offs that (by construction) apparently don't affect the pros and cons. There is no reason to choose one of them over the other. If you feel one of them is better than an other, then your pros and cons were formulated incorrectly. For example, if you feel that one choice is better than an other because the other makes you a cold-hearted a**hole, consider the effect it may have on your interactions with others and recalculate the pros and cons taking other peoples' perception of you into account.
 
You now know how to correctly (ie optimally) make any choice ever, from choosing a move in chess to what to say to your romantic interest. This procedure is often time-consuming though, so you may have to recursively apply this procedure in order to choose whether to apply it.
