Can the web browser war return, please?

Looking for an ARC Browser replacement in the next few weeks will be a hassle. In OS 27.3 betas, Safari is getting vertical tabs. Fine. Bookmarks management on Safari is weird. And is Safari’s rendering engine any good in 2026? What do I lose if I go the Google Chrome route? I don’t expect Google to add Siri AI features to Chrome unless the partnership with Apple ask for it. I still don’t see a viable alternative to the ARC Browser that is not buggy or laggy. What a pity in 2026.
