AdGuard and Wipr were the best up until now IMO but there are minor annoyances with both that bothered me for a long time. AdGuard doesn’t have a cookie popup blocker, at least in the free version. Wipr has this bug where archive.is/ph backups of Reuters articles display as a blank page. UBOL solves both and is 100% free.

I’m curious how it compares to wipr. I tried a few other addons and none of them worked very well, but ever since installing wipr it’s been flawless.
