I haven't noticed this myself, and I use both extensively on a daily basis. I currently only use Chrome for work because of Google Meet. Drives me batty that I don't have a choice there.

Same here, can't stand the fact it's taking so long to get Hangouts support on newer versions of Firefox.

I have the opposite problem somehow. Chrome is incredibly slow and pages take dozens of seconds to load. Firefox feels so fast and responsive. I think the issue is due to adblock though, which I keep off of firefox.

Try using uBlock Origin on Chrome next time. It's way more efficient than adblock.

Keep giving it a try every now and then: there's a lot of focus to improve in these areas.
