I think it's still too early for such discussion for the Emmy considering both TAR and Top Chef have a choice of 2 seasons to submit for nominations(TAR 17-18 v.s. TC8-TCM3).
I watched both shows and they're all great.
TAR 17 --> No one could forget how 2 female racers finally won TAR
TAR 18 --> Great places, great adventure, great experience and still some great promising legs to go
Top Chef 8 --> Some surprising eliminations but after all, great competitions with slight mistake cost you the prize
TCM 3 --> Normal Top Chef format with weekly eliminations and great chefs competing...been expecting this since TCM 1
Based on few years' of nominations, American Idol-Survivor-Project Runway-The Apprentice could be the 3 other nominees(Considering no other good-popular shows come up before September).
So, the other nominee that probably have a chance of winning would be AI 10 and Survivor...Both shows have a redeeming feature this season compared to the last season's.
I don't remember watching any shows able to compete with the 4 great shows(AI, Survivor, TAR, TC).
Whichever one of 4 big ones win, I can still be happy...
