Could someone outline why 6WD would be good for this year?
Tank drive has 0 turn radius.
The reason why teams tend to go with 6WD Drop is because it shortens the effective wheelbase, reducing wheel "scrub". Basically it makes it so that the robot is able to turn without jumping around or stalling.

Mecanum drive can be just as fast as any other drive system, its all in the gearing.
