I should have voted "other" I love both house Lannister and Stark. But I have read all the books up to date so i'm going off of that and not the HBO show. I like the Lannisters because of tyrion, his intelligence is so sexy and despite all his deep hurts he's actually a really sweet guy, his storyline is one of my favorites. My second favorite story line is Arya (i'm not sure where the show is at at this point so i won't give any spoilers) but i could honestly just read a book dedicated to Arya's exploits. Third favorite story line is Dannerys, Fourth favorite is Sansa and what eventually happens to her. Honestly guys i don't want to be "that person" but the books are so flippen good, if you like the show please please please take the time to read the books, (it's a great cheat to see what's coming in the show) you will not be disappointed, my little brother got into the show and i actually gave him my old nook with all of the books on it b/c i got too excited wanting to discuss stuff with him and i was like "omg where does it leave off at the season finally?!" and i had such a hard time not spoiling it.
