1x is the better choice if you ride primarily off-road, value simplicity, or plan to bikepack. The chain retention and clean bar setup are genuine advantages on rough terrain. Choose 2x if you ride significant pavement, prefer tight gear steps for cadence matching, or live in flat terrain where the 1x's wide-range cassette has unnecessarily large jumps between gears. For most classic gravel riders, 1x with a 40T chainring and 10-46T cassette is the ideal setup.
