OTC ???? :0) I definitely have favourite characters but I go through phases. I get all obsessive about a character (like Duo, or METHOS) and then I'll have a break from the fandom for a bit and suddenly want something different (Trowa fics for example and um still Methos). These 'canon' pairings are my only true constant and even with them I will occasionally be seduced by good writing into reading something different.
