I'm a hobbiest video encoder (mostly I like to experiment in backing up my DVD collection), and I recently switched to using AV1 over HEVC.

I've found the ratio of a fixed quality vs CPU load to be better, and I've found it is reasonably good at retaining detail over smoothing things out when compared to HEVC. And the ability to add generated "pseudo grain" works pretty well to give the perception of detail. The performance of GPU encoders (while still not good enough fory maybe stringent standards) is better.
