As others have said, there are advantages and disadvantages to both types of schools. I can give you our experiences, if you're interested.
For myself, I went to a big city for college after growing up in a rural area. I *thought* I wanted a small LAC so I wouldn't be overwhelmed with life in the big city. It took me a couple of years, but I eventually learned that I didn't fit in at that school. At this private LAC, I was "the poor" student (financially), and I could NOT relate to the lifestyle of the other students, nor they with mine. I transferred during my junior year to a state university, and I was much happier there. It caused me to graduate in December instead of the previous May like my friends did, but it was worth it to me.
My two oldest boys are introverted and not confident in themselves. I knew that we needed small colleges for them. They are both attending small private colleges (one @1500 students, the other @ 3000 students), and it has been a good fit for them. They receive the individual attention they need to succeed, and they aren't overwhelmed with the huge student bodies. However, the disadvantage is that the course offerings are limited. For example, my rising-senior son needs a class to graduate next May, but the class he needs is offered only on odd-numbered years in the fall semester only. Oops! Still not sure what we're going to do about that one. We will be calling the advisor this week. (LOL)
My third son is very outgoing, "everyone's friend", and very confident in himself. We knew he would HATE a college like his older brothers attend. He is at a large state university (@30,000 students) and he is thriving. He has found a niche in the honors program at that school, so in a sense he is in a somewhat smaller clique within the larger student body.
Different strokes for different folks. But I am convinced that there *IS* a perfect fit school for each and every student out there. Colleges are so different from each other, just as different as students are different from each other. It really is worth the effort to take time to find schools that fit the students.
