I am in agreement with the others here. The RPi kernel is the best kernel. They only do support for their devices and does it well. Plus there is a huge community support. It takes a long time for upstream to offer new features if they do at all.
The last time I booted the upstream kernel to test their new v3d addition it seemed to be ok but running kodi-rpi with HW decoding was a no go. The HW decoding is the one thing that is important to me as I am a big movie fan. Since firefox 116 came out with pi4 v4l2m2m h264 HW decoding I am testing youtube with the enhanched-h264iy firefox plugin and it seems to be doing ok playing mp4 videos.
Look at the difference playing the jellyfish-40-mbps-hd-hevc-10bit-mkv test video. Notice the cpu %, speed, and temp playing with mpv using SW and HW decoding on my pi400 on htop.
