fdiron good climb rate in G10 means just an ability to commit suicide later when you try to dive on your enemy. LOL.
At least I find G10 a totally useless plane. If you want to use it's good speed to your advantage, you can't turn or hit anything anymore.
If you choose to remain slow and try to get shots on evading planes, G-6 fits the job much much better. It even handles better at dives.
My assessment of the G-10 is that either it's porked bigtime in AH or then it was a big design failure in real world. Or maybe it was designed primarily for buff hunting and was not suited for furballs. Which is probably true.
Of course in AH it doesn't even hunt buffs very well since they outmanouver and accelerate it at over 18k altitudes. I had a funny encounter with a lancaster at 20k where he first outturned, outaccelerated and shot my engine oil when I overshot him from below (I was in 262) and when I finally managed to turn, gain speed to bounce him from his belly again and hit him with 6 30mm hits, he still kept on flying and incredibly also shooting which is funny considering I peppered his whole center fuselage, starting from the tail section (took only a vert stab) with 30mm squirt on that pass.
Finally I managed to get a ping on his wingtip while he was flying 340mph in the lancaster (according to film) and he flipped over and exploded.
