This was a tough one because I like both for different reasons

GAH, DON'T MAKE ME CHOOSE!! I love them BOTH equally! >.<

<333 always!

Still David. :)
I do think Matt's a great Doctor though.

Wow, this is shocking! Equal for the first time ever!

For me David gonna be the best doctor forever :)

David is the best, but I like Matt too!

He's as mad as a box of frogs ^^

I can't choose!! Can't I enjoy both equally? I didn't think anyone could replace David Tennant but I love the new guy to bits.

I DON'T KNOW I DON'T KNOW I DON'T KNOW!!

Nobody ever ask this question again; I can't choose!

10th will always be My Doctor. <3

Matt is amazing!

Matt has grown on me a lot. When David first left i knew whoever played the next doctor would have some big boots to fill, Matt does an excellent job playing the doctor.

i prefer both but matt has something david hasnt got

Love Matt !

Matt Smith is an excellent Doctor, But David Tennant us the best doctor. His doctor has a perfect mix of madness and sanity. Matt Smith's doctor is just mad.

But they are both AMAZING!!

FOR GOD'S SAKE DON'T DO THESE QUESTIONS ANYMOOOOREEEEEEEE!!!1

David Tennant was brilliant in the emotional aspects and Matt Smith is amazing at giving the words character. But, overall they are so, so very close to be the same. It was super doper hard to pick my favorite, because I love them both. But, I chose Tennant just because he was... I'm not sure the word I'm looking for actually. But, I'm glad David left when he did. After Rose was stuck in a parallel universe it just didn't feel right the 10th doctor traveling around with other companions, because he said he'd be traveling alone. So when Tennant left (his emotions were the best there) I was looking forward to Matt Smith, but I was also extremely sad, because Tennant was such a great Doctor.
But, Matt Smith is also brilliant.
Any Doctor is.
