Workaholics has been hit or miss for me since about season 3. Broad City is hysterical along with Key & Peele on Comedy Central.
For me, I go back and re-watch Sunny almost constantly. The later seasons do kind of fall off, but they still hit it out of the park with their nonsense at least half the time, even in the "bad" seasons. This season where they're all binge drinking on the airplane is HILARIOUS. Pretty much whenever they get black out drunk makes for good tv.
That being said, I think The League has become more consistently funny, but they've gotten away from the sports aspect that kind of drove their sort of friendly, witty batter and it's more about their lives. Which are boring, let's be honest.
