Brave. Vertical tabs, privacy, everything sync is e2ee (unlike eg. Edge).
Vivaldi may also be worth a look. Similar setup: User-oriented team, vertical tabs, e2ee sync. If you like a thorough browser history, I think Vivaldi keeps a more detailed browsing history than most other Chromium browsers.
Brave is VC funded and needing to extract a billion of value. Just like Arc.
