It's faster than Firefox.
Also it integrates better with Google services.

You speaking anecdotally or do you have data?
Rendering/JS performance seems reasonable nowadays, but the UI has weird skips and freezes fairly often.
Maybe one of the extensions I typically use in both works differently in Firefox.
On Windows and macOS Firefox is a bit more competitive, but important benchmarks such as JetStream and Speedometer still have Firefox easily beat (note the inverted score axes).
That doesn't mean Firefox is slow per se, it just means Chromium (and WebKit) are faster.
On Android I use Firefox for its addon support, but the UI is notably more glitchy and buggy than Chrome's.
If a website uses enough JS for that to matter, it's a problem on all browsers
Do I prefer the modern "let's ship a JS renderer with every webpage" approach? No, definitely not. Unfortunately, quite a few web applications and websites u visit disagree with me.
There's also a perceptable difference in terms of browser responsiveness outside the page itself. Firefox seems to take longer to process UI input in my experience, for reasons I don't entirely get. There's a slight but visible delay before the page starts rendering that Chrome doesn't have, and that small delay adds up when you're working in web UIs fir a significant part of the day.
And I haven't found the Google services integration to be all that deep or interesting to matter. In fact, I'd found the opposite to be true: it's gotten in the way. Having the browser log into your Google Account directly has led to some confusing behavior, especially when signing into a second account via some webapp, which sometimes changes how the browser is signed in.
Regardless, I think we all would be better off with a bit less integration of Google services in our lives.
