Transtech designs are considerably different than BM Maximals. Yeah they follow the same theme of 'mix of the organic and technological' but the engineering plans and concept art do not share the same style as BM from a toy design point of view.

The only Archer toy that I do like, although the robot mode has some dire flaws is TM2 Megatron. The other toys are pretty meh and lesser toys than previous years specifically the ones you listed which design style was clearly followed on with BM.

I will not get into the Profit = good toy line debate as that is just silly.

Anyway I will stop now before someone decides to kill another horse in vain.
