With you on that. Hasbro Rodimus' face is jsut fugly. I can tolerate it b/c of price but it is as you say inferior. Takara did stuff up on the first run however and although they fixed it, it doesn't change that MP-09 is bettter than Hasbro Rodimus. Hasbro also does not have trailer which while you barely use is a nice touch and always nice to have. I fight myself over the question of the trailer and for G1 at least, I think it's important unless u do creative stuff like FP or Maketoys with the trailer.
In terms of rest of MPs
MP1 > Hasbro
MP2 - no comparison but lovely repaint
MP3 < Hasbro; b/c Hasbro released a non-green version - will reverse with MP11 however.
MP4 - no comparison but easily superior choice to MP-01
MP5 - no comparison
MP6 > Takara, the yellow eyes and cheaper paints just don't cut it.
MP7 - no comparison
MP8 < Hasbro subjective on which your a fan of but I'd say Hasbro's had more gimmicks so it wins but my personal preference is MP8 with the cartoon which is what most of us really grew up with and made us like the line
MP9 > Hasbro; minus the problems fixed up in the remod
MP10 > ?
So of 5 comparable points
Hasbro: 2
Takara: 3
But with one reversing it's going to be
Takara 4 > Hasbro 1.
So I would argue Takara is still a better bet. It's also more likely to have QC problems ahead of Hasbro b/c it generally (unlike other lines) releases MPs first.
