4x4 is nice, but my stampede gets around just fine on about everything.
Plus it's great on grass of almost any length, and great fun in skate parks.
The rustler is also great but has a bit less ground clearance.
All the vehicles mentioned are good but most come with a much higher price tag.
I've acquired quite a few RC's of may scales but for all around bashing, my stampede is my funnest truck.
Not to mention the stampede is near unbreakable and cheap to repair if it does happen to break.
Here is a little video of my pede bashing in a few locations including a skate park..............
