LBRY is a neat idea, but all the wacko extremists that managed to somehow get kicked off YouTube have taken it over and scared off most of the sane people. There are some good tech videos that still get mirrored there, but overall it's not a good experience.
Peertube seems like an even better idea, but so far it's catching on even less. Maybe someday it will get popular enough to be great, but for now it's kind of just not very useful. The big thing it's missing that I think is stopping it from catching on is an effective way of finding videos you might be interested in, especially from smaller instances.
