Not going to lie the Kotobukiya kit looks better than the 3A Rex and for significantly cheaper. It's a lot smaller though. I'm starting to really lose hype on 3A Rex. Hopefully new pictures of it as it starts to surface in September will make me not regret the purchase.
I've been bummed about it since it's been shown with that awful green color. I still want it, just my excitement for it has vastly diminished.
