I'm a massive hypocrite, if you asked me what kind of base you should run, I'd say 99% of the time run a 6wd, 1% a crab, and never use holomonic or mecanum.
That being said, let me contradict myself. There is no perfect drive for all games. Your team must analyze the game, determine what the requirements are for your drive, and pick based on that. They all have benefits which come at varying costs.
Even though I'm pretty darn sure we'll run a 6wd next season, my team will still stop and analyze to determine if it is really the best choice.

A crab can be switched to a skid steer pretty easily in just about every application of it I've seen. Sure, it's obviously not the lightest and most efficient skid steer when in that mode, but it is equally as functional.
