I like Nebula so far, but most of the videos are also on YouTube. I signed up for a promo through a channel (I can provide some if you like), so I got it for essentially $2.50/month.
I also sub to a few channels on Odyssee, and a couple on Rumble. If you’re good at searching for stuff, PeerTube can also work, but I personally haven’t found anything I really like there.
Only about half of the channels I follow are on YouTube, so if I really needed to ditch it, I could.
