People (especially video professionals) tend to not use QuickSync because the quality is pretty low and you have very limited ability to tune the results. It's optimized for real time encoding and not high quality or small file sizes. I think on H.264 it's about equivalent to the x264 veryfast preset, no clue how the H.265 quality stacks up, only the more recent Intels even support that. NVENC has better quality, but still a software two-pass encode will give much better results.

It's the same on these phone chips, sure the encode is much quicker, but it's not a fair comparison because you have much more control over the process using software. We'll have to wait and see how the quality and file size on the M1 encoder stacks up.
