I used to use Invidious on my desktop and NewPipe on my Android phone. Even tried FreeTube for a while. Everything worked great except managing subscriptions was a pain. Each device needed to be updated manually.
Then I discovered Piped and now use this exclusively. It's open-source, blocks ads, has SponsorBlock, and subscriptions. You can use it any browser and use the LibreTube Android client.
All the benefits of FreeTube, Invidious, Newpipe -- with the added benefit of subscription sync across all devices.
