I think the biggest downside of the Ublock Origin’s MV3 version is its lack of dynamic filtering that would block [significantly more](https://github.com/gorhill/uBlock/wiki/Blocking-mode) unnecessary 3rd-party scripts compared to the default easy mode. If you’re not using it, the differences are smaller and probably something the user won’t notice.
