I would think Naruto's order of importance would go :
1. Sasuke
2. Sakura
3. Kakashi
4. Jiraiya
5. Iruka
I'm not certain though, I guess it's all up for debate, that is unless Kishi made an actual list.
I gotta disagree here. Iruka isn't that low. :c I don't think lists like this are fair to begin with, but if anything, Kakashi should be there.
Sasuke and Sakura are equal in importance IMO. She's a love/love interest, and he's a brother. Two different bonds in his life that are difficult to compare. They each fill Naruto with each type of love. Although...Sasuke never was a really good brother to begin with..

I know they have the past in common, but that's at least not what I am looking for in a relationship. That's just my bias opinion however, Naruto will apparently go to the end of earth to save him, it just means that I can't understand what Naruto sees in Sasuke.
And also, Sakura's relationship with Naruto wasn't tested in the same way it was with Sasuke.
