Omni-drive is the ability to go any direction without turning. Two classes are swerve (turn the wheels) and holonomic (non-turning wheels with rollers on them).

6WD vs 4WD is a little harder. 6WD doesn't bounce as much as a 4WD while turning. However, the exact benefits depend on the type of 6WD--dropped center, coplanar, and coplanar (omni-in-the-corners) have their own quirks and disadvantages, but all have their advantages.
