Hi guys.. Sorry to revive this topic.. But I need some informations, or some declarations from people who flew those airplanes, if it's possible.

I'm a student, and I'm doing a research on ~50 seats regional jets comfort, comparing some points like seats (dimensions, reclination), aisle (dimensions), noise, temperature, window size and position, in flight entertainment, ilumination, etc.

I need to know what do you think about these points between ERJ-145 x CRJ-200 x Q300 x ATR-42... I only flew one of them, but a long time ago... Don't need to be exactly numbers, just yhow you feel inside them, and what could be better, for you.

I didn't find a better place to ask this.

Hope you can help me.. I'd be very very grateful.

Sorry for my english..

And thank you very much.
