I kind of liked Suburgatory when it started (mostly because Isabelle was my favorite character on Weeds so i figured i should give her new show a chance) but it's so one note. Every episode is the same. The city girl doesn't like the people in the Suburbs and the people in the suburbs don't like the girl from the city. Only so many times you can write that into an episode before it gets stale.
Modern Family is perfect.
And as for Happy Endings, i didn't really like it when it started but it has to be one of the funniest shows on TV right now. Not to mention that finally there is a gay character on TV that i can relate to. I am Max lol. Usually all gay characters are the super flaming annoying kind (Glee).
