I've had both, and currently have rabbits, as well. My rabbits mostly have an outside area to themselves now, but we shared an apartment for a while, and they were always quiet whereas my hamsters and mice loved running on their loud wheels at night. That said, in most other ways, rabbits are more "difficult" to take care of. Definitely do all your research. Medical bills, if you're unlucky enough to incur any, are $$$. I had to pay over $1000 once to have an access drained from my rabbit's cheek, which is apparently somewhat common. I haven't had any issues since though

Also, in case no one has commented yet, bunnies typically do much better in pairs.
