This is like asking me to pick my favorite meat! Haha. I usually go for over easy, but I also love soft-boiled, and baked. Basically any method where the yolk is still runny. Love them scrambled too, but I remember reading about the oxidized cholesterol being bad for you, so it's not my usualy method (then again, I think it was from Mercola, so it may be bunk).
I like breadsauce's serving suggestion. I like scrambled ones with salmon, dill and some type of dairy like cream cheese. Bagel and lox replacing the bagel with eggs basically, haha.
