You’ve perhaps compared the wrong niche though. Game streamers are the Harlem Globetrotters; you’re not there to watch excellent gaming, but entertaining gaming. Whereas esports are the equivalent to competitive sports.
That said; I too struggle to care about watching either. Even my old boss Limmy, no care for watching him stream.
This is just one man’s take, but, Neds and Chavs aren’t quite the same (I grew up in Glasgow but have also lived south of the border for most of the last 18 years). Neds are criminals, Chavs are anti-social. The equivalent to Chavs in Scots would be Jakey, Bam, or Gadgie.
