Except Di2 shifts perfectly every time and the battery means that you are thinking of charging in terms of months rather than hours. Good luck doing a back country multi-day on AXS (hoping that it can be recharged from a power pack) where as I can confidently do a six day trip and a 14 day work phase without worrying about my battery life with Di2 on my bike. Yes wireless would be great but there is a good reason that Shimano stuck with e-tubes and a battery.
