I will say, the Battlechargers are disappointing. The robot mode looks ace, but neither car mode tabs together properly. Shame, but they're essential goons for the Infiltration shelf and the robots do look appropriately mookish.
The cars are awkward to fit together, infact most of the recent cars have felt a bit fiddly to fit together, but the Battlechargers look great together in robot mode. Good enough that I put away the club ones and I never thought that would happen.
Transformations do seem to be getting more complicated to me.
It's a hard comparison. They're doing very different things as toys. RTS is probably the better toy, but SS86 is pretty much the perfect '84 update. Actual Porsche mode, cartoon/comic model accurate robot. I wasn't expecting SS86 to hit this hard.
I suspect the feet out the back are so the designers can have plausible deniability about the alt mode, because the Porsche is more probably more accurate in shape than the '84 toy was otherwise.
I've had to admit defeat with the car mode. I can't get the back end to fit with the roof. I need to find a transform video. It's almost there but I'll be buggered if I can get the back wheels to fit in. I can't see what I'm not doing. Car mode does look excellent though.
