I've driven both types, and if the game calls for climbing or pushing absoulty go for 6 wheels. But, if you want to go after balls or otherwise be quick, 2 wheels are much easier to drive at high speed then any other setup I've seen.
And mark my words, one day FIRST will put out a game that encourages speed and manuverbilty over bulldozing.

2WD with four skid plates will be more maneuverable than most 6WD systems, this much is true. But, when 6WD is implemented very carefully, it will only be slightly behind a 2WD setup, the loss of agility shouldn't be overwhelming. On the other hand the difference in pushing power between 6WD and 2WD is rather substantial.
I'd be willing to give up a small amount of turning ability for a large amount of pushing power any day. Give a little, get a lot. The decision seems simple.
Also, it's hard for me to envision a game where pushing power isn't rewarded in any sort of way. Then again, I'm sure I said this before the 2001 season...
