It's simple and simply works
I bought this crankset not for a fancy new XX1 bike, but to convert my current Santa Cruz Highball Carbon into a dedicated 1x10 bike. I used this crank (156 Q-Factor) on the Highball with a SRAM 11-speed chain, 10-speed X0 type-2 rear derailleur and 10-speed cassette. I have never, never dropped my chain. Even on my hardtail and the ultra-rough Southern Utah desert the chain has never come off. This crank is good for a 10 or 11-speed bike and is perfect. On my 29er I use the 32-tooth ring because I often do 5+ mile climbs. Anywhere else I'd probably switch to a 34-tooth, especially for racing in more flat terrain.
