I love the Leader Class figures. At this point, ROTF Optimus Prime, and ROTF Starscream have been my favorites. (I haven't opened Sentinel Prime or Bumblebee as of yet - and I buy second LC figures of almost all the characters). But Ironhide (and I have yet to open him as well) looks to be the best ever! And he's on scale to the HA car figures. How cool is that?!
