I think your copy is as good as the Keller and would come back a 9.0 but it will depend on what the folks had for lunch, I'm afraid. What they're accentuating/ focusing on at the time. Just after coffee, I'm sure his spine corners, or should I say, the lack of spine corners, would have been noticed.
PQ on my 22 is CR/OW at best, I'm afraid. But for some reason, the 23 is much better and 24 looks white by comparison to the other two. Being the proud owner, maybe I am a little jaded, but for Green Lantern, isn't that the right colour to be?
