Cream of da crop:

Avengers

Guardians/Winter Soldier (two totally different films that surpassed my expectations)

Iron Man 3

Iron Man

Thor

Average to below average aka the ones I don't care much for:

The First Avenger

Iron Man 2

The Incredible Hulk

The Dark World

I fully expect Age of Ultron to be the best as everyone who has read that script has said it's Godfather Part II/Empire Strikes Back/Dark Knight level of sequel which is saying something cause I feel that way about Winter Soldier.

Also want to say Winter Solider/Guardians are coming for Avengers' crown cause to me it's almost a 3 way battle royale as to which are cream of da crop. Avengers has a slight edge due to the last 30 minutes and getting see the superhero team up I dreamed of as a kid.
