I spent my first year on campus and my other two years off, and I think both have their merits.
On the one hand, I'm very glad I lived on campus in my first year because it made it so much easier to meet people, organise get-togethers and just generally get used to the university lifestyle. On the other hand, I couldn't have gone back to campus for my final two years, and overall I enjoyed being in a house off campus much more. It felt more like real life on account of being in a normal house, and obviously the best bit was that I was living with some of my best friends.
So, off campus is better overall in my opinion, but on campus is probably a good bet for your first year.
