Moody, definitely. He knew his job and how to do it, and he knew he might die while in it. I can't see how Snape helped Harry through the Order. He helped him defeat Voldemort, but it was under Dumbledore's orders individually. _________________ Fact 1: Moody rocks your socks. And mine too.
Fact 2: Ron rocks everyone's socks. Except Dobby's.
Fact 3: Harry and Hermione are not meant to be together. :'< Stop the myth-spreading.
Fact 4: Snape > James.
Fact 5: Grindelwald > Voldemort.
