Basically, stadium trucks can withstand more bashing, are more forgiving and are easy to drive.

Buggies can handle huge air and can be a little more aggressive on tracks.

Don't get me wrong, both can do jumps and handle well in tracks.. just some more than others.

What exactly do you mean by climbing? Huge dirt piles? Monster Truck?

Both are pretty fast and you can't be dissapointed with either of them. Just choose the one that suits you best.

My Evader ST is still awesome so far and im not yet bored. They have loads of power from the start (those damn wheelies flipping the car) and can eat a tank of gas (75cc) in 10 minutes if you push it. 15 if you're just messing around in your backyard.
