It's apparently genetic. It just tastes like shit to some people. When I was a kid, I actually hated it because it tastes like soap. Oddly, I now love it, but I still do think it tastes kind of like soap. I've just learned to like that particular flavor of soap, I guess.
Also, I forgot to list basil. My favorite is sweet basil, specifically for pesto and pizza margherita. I generally wouldn't use sweet basil as an all purpose herb, though. I also like lemon basil and Thai holy basil. Why is it holy? I have no idea. But it's pretty good in the dishes that use it.
