Should I choose colleges based on how much they care for undergraduates?

As @happy1 notes, you can get a great education at either. While smaller schools may have smaller networks, they may also be tighter.

I think the bigger thing to consider is how you think you’d learn best and where you’d be happiest. If you learn better when you can participate more in class and have a relationship with the professors and other students, you might be happier at a LAC where this is the norm. On the other hand, if you prefer some anonymity and having more options, that might not be a good choice.
