I opened up my United one yesterday. I went with United because I intend to be a United completist, and will only get a Hasbro release of the same figure (and in tandem at that), if it offers something compellingly different, or for army building.

I feel that Classics et al, in and of itself, is generally an effort to give greater cartoon accuracy to all of the figures, so I don't understand a preference toward toy accuracy. Wouldn't the original toy fulfill that need? Wouldn't every difference between the new and the original reduce toy accuracy?

The head mold, regardless of color, looks much better in person than in pics, and I agree with Paul that the presence of the hook easily shows that Inferno could have had a ladder, and also that said hook is cumbersome. There is some other subtle remolding, specifically the forearms and toes, which don't detract or add much. As to Paul's complaints of looseness, I noticed drastic differences in hip looseness between multiple instances of Hasbro's Inferno. My United is fine.

Other than the head, I don't think there's much difference between Hasbro and TT (unlike Jazz & Tracks), so I'd suggest choosing solely based on head preference or price.

I like the Inferno mold, and thus, I like this one too. Another great inclusion to my Autobot car collection.
