The difference is the angle of the outer rollers. Omni wheels have their rollers round sides facing at 90 degrees to the wheel's roundness. Mecanums have their rollers at about 45 degrees (though this is variable). If a team has mecanums, you will have a harder time pushing them (due to the angled rollers and the power--four motors available versus two at any given time for omni's). However, it is still possible to push mecanums around, it's just a little harder.
