>>8213662Unironically Legends scale. Some of them feel like the real MPs these days. They won't break the bank if you buy a handful if yo just want to dip your toes in the water.
TF:E Prime is excellent and is built like a bludgeoning instrument. It looks great and despite not being as flexible as MP-44 he can hit all the good stoic Optimus poses.The Transformation is pretty unique for Prime.
Fanstoys is one of the favorites, but have some issues with build, QC, articulation, etc. I highly recommend Road King, their Motor Master, as a standalone piece even if it is a clusterfuck to transform.
Take a peek at the MMC Ocular Max and Maketoys Re:Master releases if you want some clever MP bots that do the job. MT's are somewhat not up to par but their stuff in undeniably a lot of fun to fiddle with.
Xtransbots can be hit or miss but generally look good. As far as bang for your buck they are priced competitively compared to other companies.
Check out DX9 and Unique Toys if you want MPM Baybots uses black magic to create intuitively transforming and clean bots.
MP Combiners are currently a meme and we don't have a full combiner from any company with a proven track record. The finished Toyworld/Zeta combiners that are in the scale are definitely not sculpted or built like MPs.
