The catch here is that it isn't as good - using uBlock in FF for Android for example will properly block all ad frames.

Using adaway or a pi-hole for that matter will not - they will only cause ad loading to fail (in some cases) - which sometimes results in frames showing errors on the page instead of a clean rendering of nothing with ad divs removed.

Personally I wind up using several methods - AdAway to kill most app ads, uBlock for web and Xposed to kill YouTube ads since the hosts-based methods seem to work rather poorly for them as their subdomains change all the time.

DNS-level blocking is, IMO, only a second line of defense. Nice to have for all those devices and applications where you cannot have a proper ad/tracking/malware blocker.

That's weird, I didn't get any Youtube ads in quite a long time, and only use AdAway.
