Dude out of all of those vehicles you listed there hard to compare caust there all in a different class.
8ight- Buggy
Savage- Mt
Mt2-ST
hell fire- truggy
I would stay away form the T-maxx.[:'(]
Out of all of the stuff i would choose the truggy. But not the Hellfire.
Truggy can race like a buggy Yet bash like a Mt.
Like stated below i would go with the St1.
Only 289 at tower and Is a proven winner. Needs very little work to become competive and is probably more durable than the savage.
And with that car dont worry about part support, You wont need "rarely".[8D]
But if you want to go with something from your list i would get the Hellfire or the Savage.
Hope this helps.
