I guess I never saw any difference between streaming service quality, at least using Apple TV. Though I’m not a TV aficionado either, all I is I press play and things usually start playing in sufficiently high quality.
The video quality is generally fine, but the quality of the apps is vast.
Anything that doesn't use system-provided UI elements is simply constitutionally bad. It's incredible that things that can't scroll smoothly pass basic QC.
