1x is simpler, lighter, and provides better chain retention on rough terrain — ideal if you ride mostly off-road. 2x offers tighter gear steps and a wider overall range, which matters if you spend significant time on paved roads or have very steep climbs and fast descents in the same ride. If unsure, 2x is the safer choice for versatility; you can always go 1x on your next bike.
