I think this dependent on your needs. Mechanum/omni-wheels/kiwi drive can in certain situations switch directions faster as they are closer to true holonomic drive systems than swerve drives. I would say Mechanum/etc beat swerves in maneuverability, but whether you need that much over a swerve is a different issue. If the time that you need to rotate your wheels enough in a swerve is too much, you might consider mechanum.
I wouldn't go so far as to say that if you need a maneuverable drive system and you have the capability to build a swerve drive easily that you should do it. There exist reasons not to do it even from a functionality point of view (let alone weight, actuation, sensing, etc.)
I bet a lot of us (mentors and students) got into this line of work first because we wondered how things work, and stayed in it because we thought "I can make that work better". Thus starts a life-long battle between perfection and time. So far, time is ahead. - petek [more]
