David Tennant! He is by far my most favorite Doctor. The emotion and feeling he ads to the character is so deep I actually cried when he Died. You connected so quickly with him and how he had an ever present sense to do anything to keep everything in line. Nine and Eleven are awesome too, but Nine was to rough for me and Eleven kinda of ruined the deep feelings Ten started by being into rely insane. But I love the Doctor, no matter which one.
