"laptop good for college" is about as ambiguous as "which is car is good for driving"
Depending on what your major is (and hobbies) makes a HUGE difference on what laptop is best for you.
If you are simply asking about screen size that is user preference. I had used 15.x laptops for a good 10 years and then got my 13". I initially figured I would be bugged by the small screen but it did not bother me at all and the small size is very nice. With that said I have personally used the new dell xps 13 and find it uncomfortable to type on and is too small for my tastes (fyi my current laptop is a lenovo yoga pro) but I am also 6ft 3in guy so what is small to me may be perfect to others.
If your planning taking it to class for notes, the 13. If you want to have enough room to comfortably do what you gotta do and don't mind the weight, get the 15.

In regards to what size/factor is right for you....the best thing you can do is go look at as many different laptop models in person as you can to get a feel for it.
