QuoteVanced is a well known modded version of YouTube with many features such as adblocking and background playback and many more.
Features in all versions are the same. There is a slight difference in the Non-Root however. Since the package name had to be changed, the Google Play Services won't play along. This means that you have to install additional MicroG package, in order to be able to log-in.
