Work laptop: Forced to use chrome so switched to degoogled chromium.
Personal PC:
Windows and Linux: Use librewolf on my personal machines.
iPhone: Use Firefox on my iPhone
Android: I use Bromite (Chromium based) on my Android phone.
So, it's basically using the best I could find for each job. I cannot defend either of those as the only reason I continue to use them is because I am used to the interface.
