Orange Is The New Black is pretty easily number 1... hesitated for number 2, ended up going with Unbreakable Kimmy Schmidt just over Sense8 (it's a bit unfortunate that the latter peaked at episode 4-5). Daredevil, Bloodline, Master of None and Jessica Jones are all pretty good but with big flaws. House of Cards was decent at first and got gradually worse, I didn't like Grace and Frankie at all (except for June Diane Raphael) and haven't watched the others.
In general, and with the notable exception of OITNB, I'm noticing a trend of Netflix shows having trouble finishing their seasons. Maybe they should go for less episodes as a standard.
