Kabutack definitely looks better. While I can't comment on the figure's quality, in terms of visuals, I'd definitely be buying Kabutack.

Though Kuwajiro definitely has his charms! I do wish his chibi styled normal mode was a little shorter. He seems awkwardly tall.
I do dig the Super mode, though. looks pretty neat and I was imagining the B-Fighter character before I even made it to the comparison image!

His transformation is too simple, though, and he looks a little too awkwardly stiff in comparison to Kabutack.
I can dig it though and should I both 1) Become interested in the line and 2) Find him for 1200 yen, I might be willing to pull the trigger, but looking at him, I think the Robotack line is just a lot more interesting.
However, I can't deny that both series makes me love the cute chibi robo becoming a badass fighter. Making me think of Datas from Goseiger.

So, Den-O, gonna buy a 2nd one and paint him blue?
