Pros for the Max:
1. Fuel tank - It's a big deal when just driving on road trips. It's a HUGE deal when towing. Pulling our 30' RV trailer we average ~7mpg, so every extra gallon onboard helps. It's not quite as good as the 36 gallon tank in my F-150, but it's still better than the SWB.
2. 4'x8' plywood - A number of vehicles ago we had a standard length 3rd gen Expy, and not being able to grab a full-size sheet of plywood is just annoying. It's not an every day thing, but when you need to, you need to. Needed two 1/4 sheets for a project, but when it's cheaper to grab a full sheet than two 1/4 sheets... having the option to put all the seats down and get the full sheet home was very, very helpful (wife had my truck).
3. Rear seat space- Ingress/egress for 3rd row is easier with the Max. We've got captain's chairs in the 2nd row of our Max so it's normally not an issue, but we're in a rental SWB w/o them while our truck is in the shop, and it's noticeably more annoying to get to the 3rd row past the wheelwells.
4. Towing - Forget the supposed extra couple of hundred pounds of towing capacity with the SWB. The longer wheelbase of the Max makes towing more comfortable. Both would benefit from a larger rear swaybar, but that's easy to swap out. Extra wheelbase not so much.
5. Advanced cargo management - While the shelf with ACM makes more sense in the SWB, having the extra storage compartment directly behind the seat in the Max is another bonus.
Neutral:
1. Turning radius - Its ~1' smaller with the SWB, but the max is still 2' smaller than a crew-cab F-150, so between the Expys it's macht nichts.
Cons:
1. Parking - If the SWB will fit in the garage and the Max won't...
