I'm not the person you asked, but I like it because: Easier to initiate downloads from mobile, got a nice ui for quality selection, can import subscriptions, keeps a download log that makes it easy to play recent download

Not grandfather commenter... but why yt-dlp? NewPipe is a one-stop-shop for your mobile device, yt-dlp means searching for the video on the browser and copying the URL, running yt-dlp on the computer and then transferring the downloaded video onto your phone...

With NewPipe you can be at the airport waiting for your flight, do it all on the device, and then hand it over to your kid (I'll leave out the commentary on using video to babysit them...)
