Hmmm ok let's see...
Buggy - Hyper 7
Truggy - TT ST1
MT - Revo (prob not savage)
Smaller - Hyper STe

The ones that are most likely are the Hyper 7 and the Hyper STe.

Buggy
Pros:
Super durable
Bodies and tires are cheap
Ground clearance (compared to the Hyper STe)
Best handeling

Cons:
More expensive
Stronger ESC needed
Stronger Motor needed
At least a 4s battery
$299 for the rtr

Hyper STe
Pros:
Looks
Price
Only need 3s or even a 2s
Can use a MM
Motor will be cheaper
BL ready out of the box

Cons:
Not as durable (not so bad because it could still be durable enough)
Less off road capable
Tires are more $$$

That is all I can think if right now... I'm really leaning toward the Hyper STe but I'm sure I'll chane my mind again...
