I own a Dell XPS13 9380 with Intel igpu 620 and switched back to Chromium (without the hardware acceleration patch). My OS is Archlinux, LTS kernel and my desktop environment is Gnome Wayland. Starting from Firefox 79 I had to disable webrender, otherwise youtube videos crashed very frequently. So except for watching videos, the Chromium experience is much smoother and consumes less cpu. There is this Fishbowl web browser rendering test, for Chromium I can display 100 fish at 60fps, for Firefox (without webrender but hardware acceleration) with 10fish I get only 53fps. For watching youtube videos (with h264lify on both), I get on firefox between 15%to25% cpu consumption with Vaapi but without webrender. With both vaapi and webrender it is <15% but very unstable. Note that on Windows10 for the same hardware cpu consumption is between 5% and 10%. For Chromium and youtube videos cpu consumption it is more like between 20% and 40%. So I hope the webrender is more stable with Firefox 81, but I think I'll keep Chromium for anything other than watching videos.
