So far I like Thunder best because it has the swipe left right functionality for comments.

You swipe comment left to upvote, far left to downvote and right to comment or I think favourite it.

Slide and Dank/Dawn had functionality like that and I quite missed it.

Not yet but you can get it via Obtainium for example.

That looks very different from s2dfree.cc and the few series and movies I tested were all not available anymore.
