KRL1033 for me. Obviously more room, and I love my long drawers. I saw it as a 2 bay, with some gloriously long drawers, and an extra set of drawers slapped on the side. Those big drawers really sold me, especially the 3inch one; which holds ALL my wrenches.
The extra top space is nice, but it does leave my chargers/jump-pack exposed. Co-workers have tried to use it a shelf for their things, water-bottles, phone chargers, etc. I piled them all on the floor next to the sink, and they haven't come back.

It's a good writing space, since my cart a zero room for anything else.
Moving any box is a pain. Not sure how I'd move this one. I doubt a normal pick-up would hold it, maybe an 8 foot bed? Honestly, I think a trailer might be the way to go.
EDIT: To move the boxes, I typically put two rack arms under them, lift it with two stabilizer helpers, then back a pickup underneath. It's a *****, but there's no ramp pushing involved. The flat-bed option seems easiest though, not sure how much the KRL would like getting picked up like that.
