I love KuroFai! I love S+S too, but they'll happen even without my support (they are a perfect example of Hitsuzen).
I love all the Clamp couples really. The above two, Seishirou/Subaru (can't wait for them to show up together in TRC), Fuuma/Kamui, Chii/Hideki...I'm like Clamp, gender is irrelevent! Therefore I like straight, shounenai and shoujouai.
But I do seem to like the SECONDARY couples more! Kuro and Fai, Touya and Yukito, Dita and Jiima, Ranshou and Touki, Seishirou and Subaru (well, they were technically secondary in X). Maybe it's because the primary couple gets too much exposure and my need for them is saited, leaving me to drool over the underdeveloped/sourced secondary pairing.
