#1 holds. Note by the low number of views, people are bored by this topic, and the question makes it obvious you haven't read much of these forums. That being said, it's a naive question, but not a dumb one -- I'll answer because maybe it will bring posting karma for my future questions =)
The guy who said "it depends" is correct. One way to look at it -- AKs is better than JJ if an ace flops, JJ is better if not. Of course, if you're guaranteed to take them to showdown, JJ is better heads up (see
www.twodimes.net). But wait, maybe if there are 7 people in the pot, AKs will make a lot of money off of making the nut-flush. Or there's this one -- 22 is only slightly better than AK, and so is 77, but if you know your opponent has 77, you'd rather have AK than 22.
In general, suited cards are better for multiway hands, big cards are better heads up, big pairs are better than anything, and small pairs are also multiway. There's a 2+2 book that's supposed to come out soon (look around the website) that will help with these concepts.
