Anecdotally I find Safari > Chrome > Firefox on my 2015 MBP. I've been using Firefox, despite its comparatively poor performance, for years now mainly to try to support some competition to Chrome.

The Mozilla Foundation is a bloated, politically preachy catastrophe which clearly does not prioritize Firefox highly anymore and so it feels like the whole thing is, in essence, on borrowed time at this point.
