I got an AS from a community college, and the only downside I see is that about half of my required credits were in liberal arts.
It would be the same for the first 2 year in a university. Those freshman and sophomore courses are just refreshing courses. Junior and senior years are focusing on core courses.
I got an AS from a coomunity college as well, and then transfered to a 4-year university. The 2 years in the university, 90% of courses I took were computer/maths related (my major is CS) and I did only 2 courses that were not really related in my major -- Technical writing (ENG301) and Astronomy (a science class with lab, required). The huge advantage to go through this path, to me, is the large cost reduction I must spend in order to get a 4-year degree.
