Answer? Obvious. Both. Benedict's eyes are just absolutely magnanimous. And his voice...
Sigh...Those dark curls(or not depending on his character) and the shirt he wears as Sherlock. Oh. My. God. Martin. His accent's just so lovely. And I love it when his voice gets high-pitched. His face is very chiseled and his hair. Oh, no matter what he does with it, it's just beautiful. And his eyes. I mean, wow. I feel like I'm gazing into the Soul of the Tardis. Which no one is supposed to do. But I do it anyway. Sigh...There you are. That's my answer, no two ways about it.
I think Benedict is a very beautiful,charming and interesting english man (of sure also sexy :D) I think we can call him a hunk.
While Martin is more cute... you know, the one you want to hug and cuddle and never give free! XD
