Undoubtedly, TEN. Twelve is great, brilliant actually, but he didn’t quite reach (at least, yet) Ten’s level, in my opinion. What Tennant did with the role was so unique, absolutely marvelous. His joie de vivre was infectious and his entire arc was the most tragic of them all. Such an enthusiastic, friendly, energetic Doctor became a cold, hardened man, with moments of weakness and fear, but still being the Doctor and making the right decision until his very last minutes. Allons-y Ten!

But anyway, they are both amazing Doctors and two of the finest actors of today. Not to mention, two of the biggest fans of Doctor Who ever! So glad they had the chance to play their dream role :)
