Between DJ and Stephanie Tanner who even tho they were diff'rent in age they were still kinda close sister who never seemed to be envy with each other atleast from what i saw on the show anyway in my theory, Marcia and Jan Brady never seemed to be close one sister was jealous of the other sister in every other episode, which 2 girls had the better relationship ???

dj and stephanie jan always had a chip on her shoulder when it came to marcia

DJ and Stephanie

DJ and Stephanie had the better relationship hands down i cant think of anymore TV Sister that were close except for tia and tamera from Sister Sister.

DJ and Stephanie had their moments of fighting as did Jan and Marcia Brady. But I think all of them had good relationships in general.

Well Jan and Marcia were not really that close in the early seasons until seasons 4 and 5 then they started acting like sisters who cared for each other.

That could be because of the age differences.
