Glad you mentioned this. It's been quite a while since I have used Google Chrome, but it looks like some folks are also having memory issues with Brave, which I use about 99% of the time:https://community.brave.com/t/brave-is-using-too-much-memory/134265
Both of my Macs have 8 gig of Ram, and about 99% of the time, I am only running one application at a time. When I use Brave, I never let it get down to "serious" memory issues. It seems, though (and I've mentioned this before), that the time when I have memory issues is when I visit the site yahoo.com. Besides viewing some stories on that site, when I leave it, most of the memory it consumed is not "given back". I'm willing to bet that issue is prevalent with all browsers.
I do at times run the freeware application Memory Clean while browsing with Brave, and it definitely helps with memory management.
As for Safari, I rarely, if ever, use it, as it is just too slow for me.
