I love Vanced! The only downside is that it's not able to avoid ads when casting to Chromecast.
SkyTube is a minimalistic Youtube Android client that can avoid ads when casting: https://github.com/SkyTubeTeam/SkyTube
For those of you using Android TV, I highly recommend SmartTubeNext, a Youtube client with no ads, and includes SponsorBlock[1]: https://github.com/yuliskov/SmartTubeNext
