AdAway > Adguard if you are rooted, IMO.
Since it seems you are rooted and have Xposed Framework installed, take a look at:
Amplify (I use this alongside Greenify, it is rank 1 battery saver for me)
BootManager (disable boot on apps that you don't need on startup)
CrappaLinks (unshortens links)
I also use Wanam Xposed, YouTube AdAway and YouTube Background Playback, but nearly as important as the 3 above.
