I think the advantages of both types of drive train are getting a little overhyped.

What are you going to do with pushing power on offense, shove the opponent into your zone and let them run interference on you (because there aren't any rules that force them to leave)? If a 6WD meets a 6WD in the middle of the field, they crash head to head, they lose all forward momentum, and the one on offense has to back up, turn, try to go around, get hit again, and so on. If a 6WD meets a mecanum in the middle of the field, they crash head to head and then the mecanum goes around. And since pinning=death this year, teams will be more hesitant to push mecanum bots into walls.

On the other hand, strafing in the homezone isn't too terribly important either when you can just come from an angle to score. The lanes can be entered by well-driven bots of either type, though admittedly it's a tad easier with mecanum. Mecanums on defense are good at driving in front of 6WDs and then get shoved out of the way so fast it's not funny, and as such are not a good idea.

Assuming a field that's full of 6WDs (as regional tournaments, at least here in Hawaii, usually are), your 6WD has to be buff if you want to push people around and your mecanum has to be well driven if you want significant maneuverability gains.
