As in most things, the answer lies in the middle way: stack neither health nor armour exclusively, but aim for a mix of both. You're also going to want some damage if you're looking to duel; you can be as hard to kill as you like, but if you're not putting any damage of your own out, then he's still going to win in the end, it'll just take him a while. If you're looking to exclusively counterbuild Yasuo, then Randuin's and Thornmail are pretty good bets due to his dependance on auto-attacks; Sunfire Cape is of course great for any extended slug-fest. Frozen Heart is also a good option, but only after Randuin's, which gives you a better mix of defensive stats. And then, like I say, a damage item would go a long way.

Oh, and if possible, bait out his ult and avoid fighting him during it, if you're a tanky champion. Or, at the very least, play defensive.
