LibreTube. Uses Piped as backend and has pretty much all the features that NewPipe has, including SponsorBlock.
You can create an account on one of the numerous Piped instances and log in with LibreTube, to have things synced. Since Piped is open source, you can even selfhost it, if you know how. My Lemmy instance (FOSSware) also has a Piped instance.
I'm not 100% sure, because I didn't use both in a while. But I think there was some weird "functionality" where you have to move the map somewhere near the adress you want to go to before it'll find it when you type it into the search bar.
Why that is? I don't know at all.
