On iOS, I've been using Vinegar with Safari.

I find my consumption to be way down because the YouTube site is... good, but not great, on Safari, but I can still readily consume what I like.

It also supports picture-in-picture and I've never seen an ad on YouTube in the past 3 years except when I load them on my TV. I didn't even know there was an adblock competition going on except for in the news because I've just never seen any.
