Newpipe is more pleasant than YouTube on FF Android with uBlock in my opinion. I often search find a video on YouTube, copy the share link into Newpipe and watch there.

What do you mean by pleasant? Is this primarily something for Android users?

Some things I've not seen others mention: you can subscribe to channels, create playlists etc, all without needing a Google account

I think it's only for mobile, and you can only get it by side-loading as far as I know.

If you have a $100 phone then UI is lighter as compared to running firefox etc.

Leaner. No ads in layout. Better organized. Not cluttered by buttons nobody asked for.

It's a native Android app vs. a bloated multi MB web page. Of course NewPipe and PipePipe are better. :)
