Man I wrote out a whole reply but accidentally closed it... anyway Youtube I use daily never had an issue, GH had a real bug but was caused by them just refusing to fix a specific issue. Beyond that I've never had any site that gave me trouble. I do make heavy animations all the time for websites, and Chrome is often a bit better there but only at pretty extreme limits.
Meanwhile as a daily driver though Safari hands down feels better. Every little thing feels faster from browser open/close, page open/close, tab open/close/switch, scroll, text selection, window resize smoothness, just the e2e experience is so much smoother in so many ways. Yes heavy JS/animations maybe marginally slower, but even in benchmarks it's very close.
