Bottom line
Comet is the best choice if AI search is central to how you use the web. Chrome remains the safe default for users who need the largest extension library. Arc is ideal for users who prioritize a beautifully organized browsing experience. Brave is the strongest option for privacy maximalists who want their own search index and VPN. Many users will keep a secondary browser for extension heavy tasks while using Comet as their primary research browser.
