1x gearsets, except for FS MTBs where fitting a front derailleur is impossible, is total Emperor's New Clothes. SRAM can't make a front derailleur that actually works for shit, so rather than making one that works they tried (and largely succeeded) in persuading everyone that they don't need/want one.
SRAM FD work well enough if fitted correctly, better in fact for cables where you don't get rattling levers or trimming.
1x is perfect off-road, a lot harder to drop a chain, don't have to be panic shifting chainrings when finding a 25% rock climb after a corner.
