I used ublock and it was more or less cuccessfully fighting ads on desktop, but they still were present on phone (new pipe just sucks, and I moved to iPhone anyways), iPad, Xbox and tv.
Premium removed all of them. Also gave downloads for offline viewing.
I still use sponsorblock on desktop though. And miss it a lot everywhere else.
Mandatory disclaimer. I’m Google employee but do not work for YouTube and I’m paying for premium with my own money.
