I speak from the position of being totally opposed to adding MORE electronic aspects to my bike : I was 100% against going to AXS. But the day came when my then current rear mech was damaged beyond repair, and I could not get a hold of a replacement without waiting, but they had an AXS X01 mech in stock, and I had a gift certificate still needing to be used. So I got one and put it on my Wreckoning. All I can say is : 150% pleased I did. It is exceedingly precise, NEVER a mis-shift, NEVER a problem even on muddy days, and it is built like a TANK. It is FAR FAR beefier than my former XO1 mechanical derailer. Shifting with the thumb lever is sweet. One less cable is also exceedingly nice. I think that full suspension bikes with mid to long travel will benefit much, because you will never again have a mis-shift due to rear suspension movement. It is very fast as well, allowing you to instantly grab as many gears up or down as you might want...no hesitation. Not having the extra cable is really very very nice, and I will very soon get the AXS dropper so that I can eliminate yet a SECOND cable...leaving only my two steel braided brake lines...which will be super clean and very nice. I would say that IF you truly LOVE to mountain bike, and IF mountain biking happens to be your one--true--joy, then GET on board and see for yourself. If, however, you're only somewhat passionate about MTB, and IF you don't really ride much more than one or 2 rides per week, then maybe you won't truly appreciate the money spent. But as for the benefits of AXS : it is perhaps 'thee' best decision I have made in MTB since buying my Evil Wreckoning...which, for me, is 'thee' greatest MTB pleasure I have ever indulged in.
