Standard nico is garbage in the west. YT sets the standard with its free model, so there's no contest for me. It's a shame. To be fair, I probably wouldn't want to juggle between the two anyway. It's too much of a time sink to begin with.
On YT I mostly follow John Bain (TotalBiscuit); Arin, Dan and Ross (Game Grumps); and Frankie (FrankieOnPCin1080p) on a regular basis. There's other channels that I stop by once in a while, plus all the educational stuff, but overall I've been trying to cut down on it. That said, I never actually log into YT - so there's no real commitment other than sentimentality.
