Yea, I have 4 Boeing type ratings and they are all the same to me. I don't bid one over the other for the coach seat or even the cockpit seat. The 737NG seats are much better than any older Boeing seat (old 737/757/767). Cockpit size? Who cares, I'm not jogging up there, I'm sitting. Systems? Who cares, they all fly the same. Besides the NG has better instruments than those old Boeings.
I'm in the 737 because I don't have to fly all night to some place my phone won't work for 24 hours or more.
