Web Browsers
Where you actually spend your day.
Most of these are Chromium with a different interface on top, so the real choice is the tab model and what the defaults do without asking. Arc and Sidekick rebuild tabs around workspaces and sidebars, Vivaldi goes furthest on customisation, and Brave changes what gets blocked. Firefox — and Zen Browser, which is built on it — are the ones on a different engine.
Editor's pick
If tab clutter is the real problem, a sidebar-first browser like Arc or SigmaOS fixes it in a day. If tracking is the problem, Brave's defaults do more than any extension you would bolt onto Chrome.
