Maybe I'm just an open source purist. However, I will say that in almost all tests with websites I am actually using Firefox is faster.
(Maybe not that much of a purist: I do use Chrome at work as we're using various Google products... docs, meet, etc, and those work better on Chrome. Go figure.)
Firefox has since largely caught-up from a performance perspective, although there is still some functionality inconvenience.
Of course the stated attitude toward the user is night and day - I switched back to Firefox about the same time they started integrating Gmail / Google accounts into Chrome.
When it first came out, it was almost literally Safari (well, WebKit).
I'll admit this traditional installer dark pattern seems quaint compared to what OSes regularly attack users with these days but this was the behavior of most pay-to-pack-in crapware at the time.
Chrome users looked at worse versions of images on the web for years. It is a completely bonkers performance optimization.
Chrome did kick Firefox off in web development tools though, so I can understand some people. But today I don't think there is much difference anymore. I am not web dev though. On the other hand webdevs should know about image quality on websites.
I dare say it's actually a nicer experience overall than Chrome, with the caveat that I haven't looked into battery life impact yet.
In the intervening years I bounced between the two depending on which made the most asinine UI decisions but settled on Firefox when my FOSS sensibilities and distaste for Google hardened.
