My experience with cabled discs is more stretch/wear and, contaminated or fraying cables affecting the smoothness of the cable pull, and manually having to adjust the pads and cable every so often. Granted I did a lot of riding and can be a heavy braker.
Bleeding isn't too bad when you've done it a couple of times. I do think Shimano is easier/safer to bleed, but the SRAM bleeding edge port (on brakes that have it) is a nice improvement.
I’m partial to a hydro, had 105s on my old 2019(?) Enigma Escape and they were frankly unrivalled in terms of modulation and bite. I buy the minimal to zero advantages over hydro (field-serviceability is overstated IMO), but what makes cable discs fussier? Cable stretch, wear etc.?
Other than installing a headset and building a wheel (which I have zero appetite for when there are so many competent bike shops and wheelbuilders out there), installing and bleeding a hydro disc is pretty much the only other bike thing I haven’t tried. So I’ll get them, but probably next winter when I tinker more and ride less.
