I think the santa cruz ones that go bad are the d642 as noted above, the pawls crack
Stick to d791 / 792 no worries
Just get the disc hubs, they will fit and work fine on a rim brake build.
if you 791/2 QR you can get axles for them for £10 if you move to a thru axle frame. bear in mind axles are difference 6 bolt / centre lock. You can get steel axles if you like to break things.
Bearing quality is OK, superstar specced upgraded SKF on some. Mine have lasted OK and replaced with SKF. For the price you cannot complain, just replace with high spec ones when you need to.
