G1 DEVASTATOR UPGRADE KITS

This is my first post outside the custom forums. So I don't know if this has been asked before. But I'm looking to get one of those kits for my Devastator and I want the one that makes him the tallest and more articulated. I know there's the Junkion Blacksmith and XTransbots' 2.0 both of which are reasonable. Lastly there's the Crazy Devy which I would have to buy in pieces. Does anybody have scale comparison shots next to other bots or opinions?
