I guess I agree with Oblarg that there is minimal difference in acceleration. I tried my drag race predictor (attached) for both drives and they are fairly close (would be even closer with non-standard gearboxes). However, I believe if both were in a pushing match, the Omni would still have a 20% traction advantage.

Omni 30deg, 12.76:1 Vfinal=11.58FPS, Accel= 28.6ft/s^2, T5ft=0.70s, T15ft=1.57s

Mecanum 0deg, 10.71:1 Vfinal=11.94FPS, Accel=27.4ft/s^2, T5ft=0.67, T15ft=1.52s
