This is a Tom thing! Cable disks have niche applications, much like
hydraulic rim brakes, both of which aren’t obsolete but are technological
dead ends, with the same products being sold.

Cable disks as they aren’t a sealed system, get muck into the callipers,

hydraulic.

 I am very happy with my gravel bike equipped with cable actuated disc brakes (TRP Spyre C), 160mm discs, Jagwire semi metallic pads and compressionless housings.
 Adjustment is infrequent and easy.  Braking performance is fine. Maintainability is easy.
 

I'm running Avid BB7s on my hard-tail MTB and my CX bike, I have the same experience. My FS MTB has hydraulic Sram G2s, but everything else are rim brakes besides the HT and CX are rim brakes. The hydraulics are definitely better, but not better enough to justify the hassles associated with hydraulics. Fortunately, the hydraulics don't need a lot of maintenance once they are set up, but swapping a cable for the BB7s is waaaaaay simpler than bleeding/refilling the G2s. I wont be swapping out the G2's anytime soon because they work great and I seriously only need to do any PM every other year.
