There is another type of hybrid people are forgetting about.

The Tube scorer and Ramp climber!

These are the teams who focused on tube scoring and a drivetrain to be able to climb ramps. A lot of really good tube scorers sacrifice part of their ramp climbing ability for more manuverablity. I do know that mecnums, omni's, swerve, 2wd, 4wd and so on can drive up ramps - but how reliably and fast?

Nothing beats a 6wd with a exposed wheel to eliminate any ground clearence problems. Yes thats what 1015 got guys and gals, a tube / climber hybrid!
