This is anecdotal, but my experience has been the opposite. I briefly switched to Chrome some years ago because everyone else was and the dev tools were genuinely better, but as a user it felt clunky and slow, so I switched back to Firefox. They pretty quickly got their act together wrt to the debugger and such and so I only ever dropped into Chrome for work and to this day it's still clunky and slow. I never understood why anyone would want to stay with Chrome especially with Google ramping up their shenanigans.
