It is a tough decision. I've had several AXS groups and I've had XO1, XX1, XTR and I still have an SLX kit. All of them work pretty well other than when Shimano shifters fail, which recently happened to me. SLX and GX are really solid systems that I consider a great value. In my mind, anything beyond those are diminishing returns. As others have pointed out, once properly set up, cable systems rarely need adjusting and cables last a long time these days now that SRAM corrected the cable routing/connection (years ago) at the derailleur.
I can't say AXS is 'worth it' because it is likely NOT. What I like most about AXS is the much cleaner cockpit, easier setup since there's no running cables and almost no setup required, AND the lack of cable rattle hitting the bars or inside the frame. Most of the modern bikes I've had have cable guide tubes inside the frame and that helps, but the Firebird I just sold did not. The cables were free to move about inside the frame and move they did in rocky and bumpy sections and that makes noise. So, the clean cockpit, lack of cable noise and early on the cool factor of trying something new justified it for me. As others have said, the downsides are that one more darn battery to tend to....no, actually you may have four batteries if you have a post and derailleur (the main system battery and the transmitter 2032 in the bar module) and the only way to completely avoid not being left with a shifting issue at any time is to carry a spare for each or change the coin cell in the shifter once per year.
It's great to have choices and opinions! That's what makes this forum and these discussions so enjoyable.
