Takara will most likely release most of the CW sets, maybe a little different (ie a repaint for Wildrider as they've done for Slingshot) and probably slightly different, more G1 paint jobs.

So far I'm not convinced of the need for the Takara when I have Hasbro already, however the set price for Superion is a lot cheaper than I expected, so the choice is yours

EDIT: Forgot to mention, Takara's releases for mainline figures are always later than that of Hasbro, so you're in for a little wait.
