It used to be the fastest, but nowadays I find its performance doesn't surpass Firefox and Edge that much. Actually, I haven't used Chrome much at all recently, so maybe it doesn't at all nowadays. I definitely haven't noticed it's absence now that I've been slowly returning to Firefox thanks to Google and Microsoft's constant privacy snafoos.

Popularity and being owned by google

Brand name, and people don't know any better, or even considered the possibility that other browsers exist.

Just like with IE in the distant past, I'm noticing websites that insist that you use Chrome to use their systems, lazy Devs can't be arsed to make their code platform agnostic. Or more likely, management took the decision. Where I work we have transitioned to Edge because it works with our back end systems. But there are still some SaaS systems I use that only guarantee compatibility with Chrome.

I use Firefox at home, natch.

Edit; I use Firefox on my Sony phone as well, have uninstalled Chrome but now I find that ChatGPT only works with Chrome. Agghhh

Ignorance and the unwillingness to accept change (even if it is for the better)
