Long Haul- 744, 772/773
Short Haul- 738/MD-80/90
Honestly, there ain't much difference between Airbus and Boeing short haul fleet. I personally like the Boeing series of short haul better mainly based on asthetics and cabin comforts. And people, .5 more inches on each side of your ass isn't that much, and if you can tell it, then you have concentrated on feeling too much with your bum.
