If you're thinking of the Ultremo, you might want the ZX, which comes in 700x28. I use those with light wheels for my go-fast road bike and they have been great. Good traction and no flats. I also have Marathon Supremes in 700x40. They are also a great rolling tire, and they have the cushion of being 40 wide. It's hard to compare directly with the Ultremo because of the size and weight difference. I haven't tried the Kojaks but I've heard good things about them.
