I just purchased my first Pilot Ace figure. I like their sculpts and have been on the fence about them for quite a long time, but with their bankruptcy and my renewed forays into godzilla goodies, I came away with Pilot Ace's King Ghidorah in the gold variant, which came with the set of gold figures released last year:
It really is quite a big figure. The only Ghidorah I have that is larger is the x-plus statue...the only Ghidorah figure I have that is comparable in size is nothing smaller than the GMS Ghidorah:
Ignoring my crappy photography skills, the Pilot Ace is still slightly taller.
One thing however: I notice the sculpt from the pilot ace suffers from disproportionate shoulders. This results in the left wing drooping a bit lower than the right. Unfortunate.
All in all I think I'm pleased. I like collecting Ghidorah figures and none of the ones from the "premium vinyl" companies have really appealed to me except for Pilot Ace's.
