NIR+ACO is the best SSA-based shader compiler for AMD GPUs that exists. There are many reasons why NIR+ACO is better than LLVM, and I have a long list that I've collected over the years, but the major ones are better GPU performance (faster GPU memory access thanks to better clauses and scheduling, a lot less SGPR/VGPR spilling, better loop support, slightly smaller shader binaries), 8x lower shader compile times, and smaller memory footprint of the IR. It also shows that NIR is a mature SSA-based shader compiler that helps drivers generate optimized code very quickly. And most importantly, radeonsi has slightly better Viewperf performance with NIR+ACO than LLVM, and that's difficult to ignore.
