I've been to three types of colleges, and taught at them all as well: small private liberal arts, state university, and ivy league.
Faculty at private liberal arts and ivy league probably have a lower course load than state, and class size will likely be smaller. Hence faculty may spend more time with students (very likely at liberal arts) and/or research (very likely at ivy league).
At a state school faculty likely have a higher course load and larger classes, so less time with students. Similarly, students likely take more classes per semester.
You can find wonderful and awful faculty in all three types. But the faculty course load (usually 3 or 4 classes/semester, but could be lower if the particular prof has a reduction for committee work or research) and the class size are important to look at. So is the "feel" of the faculty/student relationship - is it fairly common for faculty to involve students in their research? To have students over to their house for an occasional pizza or taco night? You'll find that at a small liberal arts college. Or are a lot of the undergraduate courses taught by grad students? You'll find that at ivy league and large state universities. How many classes (NOT credits) do the students take per term? Four is great - they can devote more time to those four (not that they necessarily will.....but for a top-notch student, this can make a difference).
I wouldn't replace my small private liberal arts college undergrad AND teaching experience with anything. Faculty-student relationships were great for me, DH, and DS who now goes to that type of school.
As a grad student I started at a state university (not a huge one). It was good, and the faculty and grad students generally worked well together. then I went to an ivy league school to finish up my grad work. It honestly was not as good a school for me or the undergrads as the other two. Many faculty were too isolated with their research, and many courses were taught by grad students. However, I have no doubt that that name on my fancy diploma, as opposed to the small state university, made a big difference in landing me several positions.
