One point to consider is the desired output quality. I recently ran
some transcoding experiments on a MacBook (2018 Model, i5 CPU) using
ffmpeg and the "hevc_videotoolbox" encoder which uses quick sync on
this platform. The results were consistently unacceptable. x265
software encoding delivers better results for all scenarios I have
tried, even with preset fast.
After the results I have had, I see no further use for quick sync
other than real-time encoding (e.g. streaming).
