Which Dr. Who is "your" Doctor?

I started watching series revival about 2 years after it premiered (on Netflix), so for me, the 9th Doctor (Christopher Eccleston) was my Doctor. I was really annoyed when I suddenly had to get used to David Tennant. But now three years later, he IS the Doctor in my mind. I wonder how long it will take me to get used to Matt Smith.

How about you? Those of you who grew up during the original series? Which Doctor is “the” Doctor for you? And how long does/did it take for you to get used to a new one?
