It might well be slower than Di2, but I doubt it is slower than mechanical Shimano. I must say I’m always very cautious with front shifts on any bike, so I would be the least likely to provoke a chain drop. I used to get my fair share of drops on 3x mtb drivetrains on rough terrain, but very rarely on road bikes. SRAM AXS has been no exception for me.
