I would respectfully disagree. Reximus Prime is just an oversized MP-08. So it has the exact same flaws. Don't get me wrong, MP-08 is one of the best Masterpiece figures they ever made, but there were definitely issues with it. In my opinion, Grinder improves on those issues, particularly the shoulder placement. I also think it has a lot to do with displays. I prefer to display my dinobots in bot mode... and I think Grinder looks better. Maybe if I was displaying in dino mode, I'd think differently.
