Vanced actually has SponsorBlock too. Inferior depends on what you consider as useful features. For me, having the same UI as YouTube with all my subscriptions and being able to find new content on the home page are of great importance. NewPipe doesn't exactly have the same thing. I never download videos or listen in the background (as I have Spotify which you can also get adfree via a nodded apk) so those aren't that useful for me.
