Security issues.
Edit: Before you reply, I know no OS is 100% secure but it is one of the advantages of linux nonetheless.
But that will also bring the problems that Linux is supposed to be safe from.
For me, they both lose details the same way, AOM is just higher quality and compresses even better, neither of which is feasible for personal use at this time. I have some hope for rav1e but it is not mature enough and also missing many features, so not using that either.
I use that everytime with film grain. Also without grains I always noticed blocky patches around the edges (which can still be found but much less) in many of my encodes.
This is what I usually use -yuv420p10le -preset 3-6 -crf 18-32 -svtav1-params film-grain=8-20:film-grain-denoise=0:enable-overlay=1:scd=1:scm=0
I’m refering to svt.
