If you're ok with OU-D and in NY/NJ, pick up a pint of Blue Marble Ice Cream (sea salt caramel is my favorite or the more hard to find strawberry). I've purchased it from Whole Foods and Fresh Direct, they have a small scoop shop in Cobble Hill (or nearby, I forget) where they have a bigger variety of flavors but kashrus is questionable since they started selling additional non-kosher food.
Blows all ice cream I've ever had, C"Y, C"S or otherwise out of the water. It's smooth and creamy, no cloying sweetness, real flavor, real fruits- not artificial. Very pricey, but very worth it. Kind of ruined commercial ice cream for me...
If limiting to C"Y, everything besides for POTF (and even some POTF flavors) is not even worth the calories.
