I own a LST2, Summit, Stampede, Mad Force VE, 3 Clods, and Baja Currently.
"based on durability/reliability, power, jumping, handling, and speed?"
Nitro: LST2
In chassis durability I know it can take as much if not more than any traxxas/HPI rig. I have cracked a couple diff cases though (coming down from 12ft high jump full throttle double back flips). I also broke a shock shaft... I bought RPM arms and still haven't needed them yet? This truck can handle and jump too!
Obviously since I own one I might be biased, but if I owned something that sucks I would say it does. I think a revo might out handle a LST, but I don't know if they are as durable.
Electric: E-revo, stampede, maybe Mad Force VE?
I have a summit and really like it for what it is. E revo would be much lighter/faster
Stampede VXL well it has durability, reliability , speed power and jumping, handling in my opinion isn't the best truck for that.. it's only 2wd so maybe it's not part of the comparison.
Mad Force VE if you want to talk solid axle. It's fast and jumps and ok handling, durability I'm not sure.. broke a rear knuckle on an indoor jump already, more testing once the snow is gone!
