Seems to be missing many 'currently airing' shows like Californication, Community, Justified, Psych, Southland, Suits, The Following and White Collar, while still includes GoT and Breaking Bad which are on hiatus.
Anyhow, I'd pick GoT.

The Walking Dead's has been lackluster since they spent an entire season searching for the girl in the barn next to them. This season's slipping too, spending 2-3 episodes talking about going to war. Why hasn't they cleared that outer yard yet. They have a huge cache of weapons and ammo, reclaim the yard.
