While Karloff is undoubtedly the most remembered Grinch (thus guaranteeing his domination of this poll), I personally feel he isn't quite the most fitting voice for the character. He lacks an abrasiveness that would've made his vitriol toward the Christmas holiday at least a little more convincing. However, he does a good job at making the Grinch sound falsely sweet as the fake Sandy Claws, and he's pretty decent when the Grinch is proud of himself and thinks he's won. While Karloff gave a deservingly memorable performance as the special's narrator, I think he's only alright as the Grinch.
Conreid, on the other hand, nails his version of the character; his conversational voice is slightly nasally, but the rough and snarly element that surfaces in his louder and more malicious moments establishes and maintains his threatening presence in the special. Combine that with great acting in his final scene and you get a very lasting vocal performance.
Holt sounds like he's really into the part (that kind of thing I always respect), and while it took me a little bit to get used to the posh quality of his performance due to the character's creaturely nature, it is fitting considering this particular incarnation's mechanical prowess.
In spite of the Grinch's relatively toothless portrayal in the Wubbulous World series, Asbury's not bad in the role by any means; he gets the image of a mischievous misanthrope across competently enough, and the gravel he flavors the character's voice with is a welcomely different touch.
The Unknown VA, however, is definitely the weakest of the bunch in my opinion. His voice is too light for the character (especially since this version is supposed to be based on Jim Carrey's portrayal) and the acting leaves something to be desired; his big epiphany at the story's end sounds more like he's got a gun to his head than him having an actual change of heart.
My vote's definitely going with Conreid, with Holt at second, Asbury at third, Karloff at fourth and the Unknown VA at last.
