I've flown both and with the exception of the FMS the 717 is hands down a more pilot friendly airplane.
Yes the windows suck but it's more spacious. FA crews are friendlier and the FO has a dedicated carry on bag storage.
No red eyes and most legs were under 2 hours.
Hated those 5:15 block on the 73 with no meals. It was nice to do a 1 and done though.
I'm 6'3 and once I'm seated it's all good. Just have to squeeze myself in the seat on the 71. Could still fit a first class tray between me and yolk. On the 73 as an B I was not able to fit a first class tray even all the way back.
