I've been riding 1x drivetrains off and on for quite a while now. Love it. These are both SRAM x.9 ten speed setups, running Shimano XT cassettes, SRAM chains. 31T ring on the hardtail, a 30t on the Banshee. Shifts smoooooove. Runs quietly. No issues so far.

Especially with the newer 11-36 cassettes, you can get a pretty good range for your needs. All depends on what your trails are like though.
