Speaking strictly low end here - but "low end" being $2500 - $3000 full suspension nowadays, I just switched from Deore SLX 10 speed to SRAM Eagle SX w/ NX rear derailleur.
So far after a handful of rides, the experience has been abysmal. First ride, SX shifter eats a cable. Everything was shifting OK before, no indication that this would happen. Dump it back at the shop (it's a brand new bike, I don't want to touch it if the shifter pod is bad) , they replace the cable, everything seems OK, maybe a fluke.
Everything shifts like crap after a few days. I say screw it and go back to my old tinkering ways. Get the SRAM B-limit gauge. Set up everything perfect. Seems OK-ish.
Next ride- Start out OK, by end of ride it's shifting terrible. Look at the cable, seems to ghost shift both up and down regardless of tension. Turns out two of the twelve cogs are straight up bent. Bend them back like truing a disc brake. Shifting back to normal. I've been extremely gentle on this bike.
Never had this happen in like 15 years of riding. I can't speak for higher end groupsets but SX is borderline unuseable for just normal riding.
Also my Rockshox Judy had a broken damper and leaking fork seals brand new (manufacturing defect? warranty fixed though I guess)
For anyone saying "well that's their lowest end groupset", the $3300 Stumpjumper Alloy comes with full SX nowadays for reference. This is like department store bike levels of reliability.
I sold the Judy and might put on an NX cassette (bike has a hyperglide freehub) just to make this thing rideable.
