I use AdGuard, Wipr, and uBlock Origin Lite on my iPhone, and uBlock Origin on desktop.

I swear there are little gaps in each that the others get, but they're very minor. When uBlock Origin Lote recently released on iOS (within the last year), I noticed a few more things blocked. I also prefer the custom element removal or uBlock and can reuse my desktop filters.

It's free, so I'd recommend adding it as an addition to the bunch.
