I don't know how anyone who has Monger could possibly say that any other HT figure is better.
Because there are some damn good ones so it's hard to say what's best!
I agree this is a beautiful piece of work. The ingenuity and detail is unmatched... but it's so damn fragile. I already snapped off one of the shoulder guards, the rocket launcher came a bit loose after I had to use a little force to get it back in (it needs to rest on the shoulder piston; it won't lock out at full extension anymore), and a rod/piston thingy just feel off when I was reposing him today... and I have no clue where it came from! Everything looks even on both sides and the piece that fell off shows no signs of breaking so it doesn't look like it snapped off from somewhere
On a lighter note I can say that he is always in a pretty extreme pose (the one I just posted is the post neutral pose I put him in since day 1) and after all of this time my stress cracks never got any worse
