I have some Queen Studios (e.g., Thanos) and XM (Shogun, Transformers) pieces that I feel are higher quality than the QS Mark 43 I have and pretty much all 60+ of my Iron Man figures. 5 years ago, statues couldn't touch Hot Toys quality. But Hot Toys has stagnated and Statues have improved significantly due to more competition - this figure even seems like it takes a step back from something that came out almost 7 years ago.
If you want posability, Hot Toys is your only choice really, but if you want an incredible sculpt and great paint apps, some of the statue makers now put out better stuff.
