Orion is the first browser on iOS that has convinced me to move away from safari. From the Kagi team, and admittedly still in beta, it's fast, rejects telemetry, and allows install of Chrome and Firefox extensions. The built-in pop up and blocking is great, and nukes YT ads too.
Still a little rough around the edges (sometimes freezes; restart it; and switching orientation is slow), but the pros outweigh the cons.
