With a bachelors from a 4 year univ, you get more versitility. You are able to hop fields a little bit more with ease, but the road is long.
At a university, to fulfill your degree plan, for any degree, you have to take a lot of English, history, government, art/fine art, and chemistry classes that have to do NOTHING with your field or interest. You will get frustrated and think, "What the hell am I taking a biology course for when I am a computer science major?" That is the school's way of trying to weed out people who they think don't deserve a degree.
Either way you go, job experience also helps. If you want to be a computer analyst, work a computer related job, even if you are selling computers instead of cars or something. Employers of recent grad look at that.
Also, GPA is a huge factor in a univ.
