For me it depends; if there aren't any comments to the article/discussion, then I'll click the article if it sounds interesting. This is almost always the case, too, if I am browsing "new". Otherwise I'll click for the discussion, and then read the article when I get to that tab (ok, most of the time read the article - I've been called out before for not reading then making stupid comments - I try to avoid that now). Sometimes on those that I read the article first and there isn't any discussion, if I liked it then I'll add a comment and upvote it. Otherwise I'll leave it alone, unless it looks like spam or something weird (if I see those, then I look at it carefully and make a judgement to flag or not).
