I enjoy RJ's- I like the CRJ's a little better than the ERJ's, although Jetblue's E190 is pretty nice.

But then again, I'm average size and tend to travel light. The best is getting your bag right at the bottom of the stairs.

The only time I was a little concerned/unimpressed was flying in a Shorts 360 that looked as though it had served in Burma flying the Hump; I've never seen a more threadbare interior.
