I haven't done a whole lot of looking. It's just the most recent thing on my mind. I used to have a Roku and it was pretty good. The more important thing is being able to stream videos from my computer(or at least my network drive), as opposed to being able to play Netflix, which I have my Xbox for.
The problem with YouTube for me is that there's a lot of great content on there that's hard to get anywhere else. I spend a lot of my "free" time listening to lectures on various topics, and nothing can compare with YouTube in the sheer volume of monetarily-free intellectual content. NewPipe at least takes away the ad revenue from YouTube/Google/Alphabet and doesn't force me to eat up my 4G bandwidth with HD video I'd rather just listen to audio for. I support all my favorite content creators through Patreon.
I know it sounds kind of scummy to free-load, but I'd have little problem watching their ads if Google hadn't been behaving the way they have and if they weren't making their ads more pervasive. Somehow, cutting myself off from the smartest people in the world share their ideas with me, just because of a moral dilemma in supporting an internet giant, doesn't seem right to me. I'd happily switch to something like Vimeo if it could compare in content, but I don't think it ever will. Cutting off the revenue stream is the only way I can have a sort of vote without losing touch with the world. My tune will change if Google can decrease the level of uncertainty in their products and not be trying to impose its corporate vision of the web. Heck, my actions might change if they stopped having the worst technical support the world has ever seen.
