I think the choice between mecanum and swerve lies in where your robot is best suited to play (offense/midfield/defense).

Offense: Swerve
From watching quite a few matches, swerve seems alot better suited to collect balls and maneuver them into the goal.

Midfielf: Swerve
When your playing the midfield balls constantly keep entering, so you need to be able to quickly "pick up" balls from your zone. And if your in the midfield, theres a higher chance of you needing to go over the bump. So if you use mecanum it seems you need to drive straight to go over on mecanum, but you can go also sideways with swerve over the bump

Defense: Mecanum
Mecanum seems better here because its alot easier to get from goal to goal and just block the goal from other robots scoring.
