In addition, Swerve won't outrun a lot of drive systems. It's going to rely on that omni-directional movement to cut out the time used in turning to make up for the lack of excessive speed. Unless you're 973 using Emperor Swerve, you're not going to be moving at very fast speeds.

These points aren't necessarily 100% accurate. Both of these will vary with the implementation of the swerve and the drive it's being compared to.
Pushing power is defined by the robots over all weight and wheel configuration, being a swerve doesn't really change much here - other than the fact that a 'unicorn swerve' (or any swerve with independently powered modules like 111's) has the issue of losing pushing power if one or more of the wheels lose the ground as the motor's power is wasted and the weight on the driven wheels will now be less - this is an issue that any drive with independent wheels can encounter.
For examples of fast swerves other than 973's Emperor Swerve, reference either 16 (In any year, but 2008 or 2011 would be best) or 148 (2008).
