Replacing foreach loop with LINQ

In some cases LINQ can simplify iterative code, and in those cases, it's a good practice to switch iterative code into LINQ.

Regular foreach loop:

var bestStudents = new List<Student>();
foreach (var s in students)
{
    if (s.Grade > 9)
    {
        bestStudents.Add(s);
    }
}

LINQ way:

//LINQ query which generate the same result as the foreach loop above
var bestStudents = students.Where(s => s.Grade > 9).ToList();

Why does it look better with LINQ?

1. Removing the if statement reduces the complexity (even if just a little)
2. For me, declarative code is often more readable
