The alternative is Samsung, the company that doesn't understand privacy nor consent, or Apple, whose phones lack uBlock support.
It’s a bit wonky and on iPhones there’s a lack of configurability, for example there’s no way that I know of to bring up a dialog to block elements in ublock, or adjust the settings in dark reader, but they do seem to work well enough in their default flavor.
The reading list functionality is less ergonomic, but tabs/pages are more ergonomic imo, and it seems to work better with webpages that safari spins it’s wheels on.
Unfortunately it doesn’t help the forced zoom that Apple forces on everything when a text box is loaded, that is then compounded when giving it focus with a cursor for writing (yes, I’ve already tried all system systems that could potentially disable that. Nothing works, Apple’s text input continues to be straight up burning garbage on multiple levels)
I’d say it’s worth trying, and sending feedback to.

Having said that, if the camera bar is an issue for you, the case wouldn't make a difference one way another.
