In my view, weight will determine 90% of all debates with all other things equal.

My team normally pairs up some sort of high-traction wheel with omni-wheels (we call them the "your momni-wheels"). We've never had a problem with the plaction wheels from AndyMark, so while the performance wheels are nice and pretty, we normally cover them with bumpers anyways, so we go with the lighter choice (rated 0.8 lb performance vs 0.66 lb plaction). It's not an outstanding difference, but sometimes every little thing counts.
