I personally enjoy GTS. I use it for two accounts. It's still alpha, so not feature complete, but it does all the basics I'd need and I find it to be stable.
Instead of Youtube or a Youtube front end, Niccolò also posts his stuff to Peertube, for those interested:

This specific video isn't up yet, but I'm sure it will be.
I know! It's just absolutely stunned. Look at my face :-| see how surprised I am!
It interacts with the Fediverse in general. Peertube follows are bugged, but Peertube is working on it. It can't really follow some Lemmy things, but van with others. Idk. :-D.
