This is how I rank the current crop of ST's. By the way, I have a GT and used to have a Rush. I am factoring in performance, durability and parts support.

1 Losi XXXNT
2 AE RC10GT
3 Duratrax Evader
4 XTM Excellerator
5 Mugan ST
6 Kyosho Ultima
7 HPI Rush
8 Traxxas Rustler

I would rate the Mugan up there with the Losi & AE if they had decent parts support.
