For me it's the first browser that has made proper tab management stick. I have way too many tabs, in the middle of the day I often have 40+ per window. The combination of pinned tabs, tab renaming, folders, auto-expiry, sync, and spaces, just works well. They have in my opinion perfectly developed the spectrum from ephemeral pages you need once to pinned pages you always have open, with many levels of granularity along that spectrum.
The rest of the browser, not for me. They have a whiteboarding feature, not sure why a browser needs that. They have AI now because of course they do.
I enjoy using it at home. The day they decide to charge $20 a month because of the AI features is the day I switch back to Chrome.
