IMO, I agree that Universe/Henkei Ratchet/Ironhide aren't that great and I too prefer the transformation sequence of the ROTF/HFTD/AA deluxe Ratchet and Ironhides.
Having said that though, the latter figures aren't exactly homages to the G1 characters nor do their designs fit in with the rest of the Classics/Universe/Generations line, so it depends on where your collecting intentions lay.
While often the line between Movie-verse and Classic-verse lines are blurred, with these two, the lines are clearly defined - Movie-verse Ratchet and Ironhide don't belong (IMHO) on the same shelf as the Classic-verse characters and therefore they shouldn't substitute for that character.
If you're a completist (of a series), you get the figure irrespective of how lame or bad it may be (such as Universe Silverbolt)
