Same as you, I also haven’t fully dipped my toes to the world of self-hosting (yet).

1. For non-animation movies/series, I wade through the popular/trending categories or read recommendation from friends, lemmy or, god forbid, reddit. I don’t really need to do this lately as my shows backlog is as long as my games backlog.
2. For convenience always. 720p is fine for me.
3. I stream. Unless it is one of my favorites I want to keep.
4. Real-debrid+Stremio.
5. Stremio does it for me. Also for anime, I have Anilist.

Hi, One Piece fan here. Yes, it’s really long and really intimidating to start. I haven’t watch most of the anime too, and never recomment others to watch it. I’m solely reading the manga (and live action).

I suggest waiting for the netflix anime readaptation that’s in production now. Logically, it should have better pace and much less filler than the first anime. It’s gonna be way easier to pick up than the first anime with its thousand episodes.
