I use Edge whenever something needs to stream on a Windows PC, unlike other Chromium builds it is capable of hardware acceleration and therefor 4k streaming. Whenever you watch 4k on Google Chrome it isn't really that high quality.
As much as I hate Edge and Chrome, ,my 5.1 surround sound doesn't work in Firefox. So if I want to watch something in surround on Youtube I have to switch to Edge. Then the nagging starts.
