Ratchet is an easy winner here.

1. Ironhide looked much the better of the two in the movie but Ratchet got beefed up in the toy version whereas Ironhide became positively anorexic. You have to pose him in such a way as to detract attention from how skinny he is.

2. Ratchet can stand flat-footed in a lot of poses whereas Ironhide always has to balance on the insides of his feet which doesn't look as good.

3. Ratchet has a brilliant, fun transformation whereas Ironhide can be infuriating to get back into vehicle mode.

4. Ratchet is a more solid toy. Ironhide needs much more careful handling and is therefore less fun.
