While the UT ones look pretty cool I do have to say they sort of look like a "What if Hasbro/TakTomy made the Predacons with todays technology".
Which in itself isn't a bad thing, but seeing as I only just bought the 2010 reissue Predacons if I was going to buy one or the other I'd probably get the MMC one.
But if the complete set ends up being a bargain basement price I might end up reconsidering.
