While true, a robot that can push is almost always more defensively useful than a robot that basically can't. I'm a pretty strong advocate of "defense != pushing", but I'd still rather do it with an XWD.

Except you lose significant efficiency in most directions, when a slide drive lets you make the primary direction of travel more efficient than the others. For example, if you have 5 CIMs, you can have a 100% efficient 4 cim forward drivetrain, while only using CIM 5 to go sideways. With a holonomic drive, you are stuck with 4 cims and the inherent efficiency losses that come with them.
