I haven't used both but I say choose swerve over mecanum. Mecanums don't have as much power and most teams write them automatically and will be hesitant when choosing a team with mecanum drive train for an alliance. However, don't listen to those people who that say mecanums are horrible. We've used them before in the past and their not that bad. They are much easier much to build and program than swerve.
