Ok, I voted for them all because I'm a cheese-aholic. Never met a cheese I didn't like :D Swiss is probably my least favorite only because I don't like the way it tastes if you eat it plain. I always eat it on sandwiches and hamburgers though. I LOVE sharp cheddar.
I notice not too many people voted for feta. I suggest buying basil & tomato feta and putting it in your salad - MMMMMMMMM. I also put feta in my hamburger meat and it is really good!
