Yeah, NextDNS is basically in archive mode. Last I looked, they had long outdated lists available, they took forever to add Hagezi and the bug reports and feature requests just keep on piling up. They seem to have a lot of billing issues too. ControlD issue releases very regularly, with full documented changelogs, active bug fixing and lots of new features. Way better. AdGuard DNS is similarly decent, but I find ControlD much faster (1ms ping for me). ControlD also have in-house cross platform software to set encrypted DNS easily, and a good stats setup. They're also the only provider who provide 'smart DNS' for free as part and parcel of the normal DNS, so you can proxy services - eg set Netflix to USA, Imgur to Ireland (to bypass the UK ban but keep loading times fast) etc.
