I use Brave and am satisfied with it. The occasional hassle involved in turning things off when a new unwanted feature shows up or when I have to install it on a new machine is worth it for uBlock Origin and the Chromium performance and compatibility.

However the theoretical downside of Brave is that as Google continues changing Chromium's codebase, there's incentive for them to make it harder and harder to maintain a manifest v2-enabled fork. Wouldn't be surprised if extensive refactors randomly happen that multiply the effort needed to merge changes from upstream while maintaining the v2 capability. And how motivated is Brave to do all this labor? At some point they're going to say the tax is too high, we have a nice built-in ad blocker anyway, just use that.

A well-maintained, funded, and focused Firefox would be a good thing for when that day comes.
