for me, i learned a lot on college...its great to be able to take classes in stuff that you are interested..thats the benefit of a university...i learned a lot that im gonna need in grad school too.
also the social aspect...u meet a lot of people and have a lot of fun...since i went to a university in a smaller city (Davis) you get to know a lot of different people and establish some good friendships
lastly in my transition from regular college to grad school my degree and the university that it is from has opened up a lot of job oppurtunities...it really helps when an employer looks at ur resume and sees that u went to a good college, even when u dont have much work experience like me...
but overall i think the college experience depends on what you make of it...how hard you study, what major you have, and how much motivation u have..
