For me yes, the 73 trips have gotten worse (more redeyes in LAX) and the plane is just god awful with the ancient overhead panel (Thanks SWA). You have to touch more switches/buttons on the 73 vs the bus to get the same results. Don't forget the poorly designed cockpit with minimal space. I'm no engineer but how does the 320 have space for 2 jumps + bag space for all pilots and the 73 can barely fit 2 bags with a jump. I've also heard the transition from 320 to 330 is relatively easy.

If there isn't a large gap of seniority between the two fleets, I'd go 320 with no hesitation.
