With 1902 we ended up going to the basic six wheel design that was a strong pusher and turned well plus a lot easier to work with.

There maybe games where mechanism will be an advantage, but pushing seems to be a major issue most years.
As others have already said, with omni's and mecanum designs, you will get pushed around. BUT what you will have is manueverability AND less stressed components. Since we have started using omnis on the outer wheels on our robots, our motors don't heat, breakers don't trip, less chain breaking/problems. But again we had to remind our driver all to often, not to waste time trying to push others around.

If you want to push folks around, your drive system better be tough.
