Swerve Drive vs Mecanum Wheel drive?

[RoboChair]

Mecanum if done well, geared for agility, and absolutely programmed FIELD CENTRIC and then practice the hell out of it can be a very competitive drive train. Anyone that does not put in the effort to code and set up a mecanum drive for field centric is wasting their time. I have seen many teams drive mecanum like a tank drive with only the occasional strafe/rotation and this is a waste of time. You can dance across the field dodging defense all day if you can just move the stick and your robot moves that way on the field no matter where it is pointed. But if defense catches up to you that's it, you must be faster! Mecanum shouldn't really even have a tank style drive mode.
