It depends on your riding mix. 2×12 is better if you ride primarily on pavement and value tight gear steps for maintaining cadence. 1×12 is better if you ride significant gravel or rough roads where chain retention matters and simplified shifting is an advantage. SRAM's AXS ecosystem makes 1×12 particularly appealing with wireless shifting and wide-range cassettes. For most riders doing 70%+ road, 2×12 is the safer choice.
