Did a lot of research on this. Watched a lot of videos and studied a lot of pics, and I've actually seen the MMC prototype at A3U. MMC to me is the best of all the Predakings out right now. Plastic quality is top notch, and the combined form, the individual parts flow together more smoothly than TFC. It captures the spirit of what Predaking should look like better than the rest.
The only flaw is an assembly error on Bovis. Here's a video of Peaugh explaining the error and how to fix it.

I did the fix involving popping the pin and reversing the part. it took me like 10 minutes to do, and all I needed was a tiny screw driver like these ones.

Good luck. I hope this helps.
