Amazon has it's issues too. Especially outside US where they do nothing to localize content and their acquisitions people buy crap in bulk.it still sucks big time when compared to Netflix or Amazon Prime. The interface is slow, bugged, and the subtitles are a nightmare sometimes.
For now in terms of UX its
1. Netflix
2. Disney
3. Apple
4. Dunno. Hulu? Shudder? Mubi?
5. literally anything
6. A block of wood
7. HBO
8. Old HBO
