Piling on here, the I think the CRJ-200s stink. I'm an o-line build and if I have to be on one of those, only an aisle seat will even fit me because I don't feel like having to tilt my neck.
The CRJ-700 is slightly more tolerable, but I've only experienced the PSA ones. I've been able to avoid the Mesa ones.
The ERJs are much better in my opinion, especially on the "A" side.
Actually, I'd even take one of the old Dorniers over a CRJ....
