I bought the Go! version. His paint job is far superior to the Beast Hunters version, especially on the doors.

He doesn't come with the armor, but I almost see that as a win because I've hated pretty much all of the Beast Hunters armor, and none of it ended up appearing in the cartoon anyway.

Transformation is very intuitive, until it comes to getting that last arm in place - then you have to dick around for a few minutes until you can get it all to join up properly.

The robot mode looks very good, as CBratron said, much better than the Knock Out repaint (and I wasn't a big fan of that mold anyway). Paint job on the Go! version, like previously stated, is awesome! Very sexy vehicle mode, really low set sports car, looks like he was built for speed! The missile you can put in the roof looks kinda out of place, but then still a lot more sensible than the armor from the BH version.

Overall, except for one fiddly bit of Transformation, very happy with this figure!
