I don't like the two JP Optimus toys, as the shiny parts on only the red bits showing in vehicle makes it look half-assed in robot mode, and worse than Hasbro's mis-matching yellows. The poor colour integrity looks really obvious on the WFC Optimus, but is still noticeably annoying on the Gen1 Optimus as well, to me at least.

At least the colours on these four aren't different enough from the Hasbro ones for me to 'have' to buy them...
