Yeah, so did I. He certainly developed better than any other character, neither was his development a bit (can't think of the word to describe how Seven of Nine did).
What development of Seven are you speaking of? The constant "I disobey Janeways order and never have to face the consequences"-development?
Back to our O`Brien fandom:

I believe he left TNG during the 5th season, which means that he and Worf are only one season apart in terms of total number of years served in front of the camera. However, since Worf was a major TNG character, he would outrank O'Brien and have more XP.
But O´Brien did already serve during the Cardassian War on Setlik, and thus was already an experienced Character before he even was shown on screen.
Worf had little background before he came to the Enterprise - he was to young.
Oh, and I just remember a nice scene, even if it has nothing to do with O`Briens "level", just with some movie trivia

:
In a DS9 episode where they found a crashed Jem`Hardar Vessel on a planet, he had a discussion with one of the younger officers (a yellowshirt, the TNG/DS9 version of a redshirt, you know) while they are climbing a few cliffs, who was worried that it would be to difficult for him:
He said something like: "Back in Ireland I climbed bigger mountains than this, so don`t worry about me". "Ireland has no mountains, only hills, Chief."
Which seems to be a reference to a movie Colm Meany played in, the title something like: "From an Englishman that climbed a hill to come down from a mountain" (I only remember the German title). The english man in that story is ordered to make a new estimation of the local mountain, and figures out it is to small to be a mountain and thus has to become a hill - but the village nearby insists on it beeing a mountain (it seems very important to them), and tries to increase the hills size...
