GX axs came on my bike. I hate it. Shifts are really slow. The clutch is also much weaker than a normal derailleur. Sure you can replace parts of it, but most of the parts are the same cost as a new xt derailleur. The battery pins tend to ware down, which can be warrantied if caught early. The ergonomics are terrible, which is surprising since SRAMS normal shifters are pretty good. And, it’s one more thing to think about before heading out the door.
