I use ublock on my desktop (with a Chromium-based brow' though) and like it. But on my phone, I just prefer to have a self-contained solution, instead of having to install other stuff like plugins.
Plus, if I can use the DDG browser, I can use the same app to generate duck emails from my phone as well, which might come in handy.
FWIW though, I think that agreement no longer applies. I getchu though, on the principle of the matter, assuming they actually lied about it. E.g., if they said, "we don't let any tracking through," without mentioning their deal with Microsoft. If they just said, "we block most trackers," and let people hype it up in their heads though, that's kind of a gray area IMHO.
You can also check out 2FAS, which recently got open-sourced.
I happened to be comparing this and Aegis so I'll add the biggest differences I noticed. Maybe it helps someone:
Aegis is Android only, 2FAS is iOS and Android and they have a browser plugin.
The browser plugin still needs you to approve via your phone/device.
2FAS has automated Google Drive backups. You can manually export if you backup via, e.g., Syncthing.
Aegis has automated "external storage" (e.g., a folder on your phone) and "Android Device" backups—the latter are stored on Google Drive too, but, as far as I understand are used via a device restore (may not be as easy to drop these in as the other backup methods).
2FAS lets you secure with a 4-digit PIN and biometrics. Aegis let's you use a full-blown password and biometrics.
I read somewhere a long time ago to keep it between 40% and 80% to prolong the battery life. That's what I try to do.
