The SRT is primarily a neo magnet upgrade of the AFX Racing Turbo, and is a good running chassis I use them with a number of my Sports Prototype, Cam Am, and GT bodies, all with tire upgrades. Otherwise, they are fast and handle well (why else would BSRT have copied it for their G3 & G-Jet?).
The problem with Super G+ are those 'pneumatic' rear tires you have to replace the wheel hubs (or use 'Jel Claws' made for those hubs) if you want to take advantage of the selection of slip on tire upgrades that are available in the market. But I have had experience with Super G+ for years, as well as Turbo and SRT, and got into the Mega G's as soon as they were available. As I only race on my home track (Tomy), I cannot give the racer's perspective.
