I've been using a bunch. I've tried liftoff, Jerboa, the official PWA and wefwef. So far, I'm liking the vibes I'm getting from liftoff.
Mizu (aka the cant shit for 3 days guy) is the only real celebrity on this platform
Being realistic here, there's no worthwhile competitor to youtube at this point in time. You have some stuff like odysee, LBRY, peertube etc. However, the amount of content on them is basically nothing compared to youtube and there's little incentive for creators to move there due to how difficult it would be to monetise your content in those places.
My best pick would be invidious which is a private & ad-free yt frontend that uses it's own API and doesn't need JS. I already use it all the time. It's good.
I salute your creativity haha
