I vote for Morgan Freeman. No matter how much Don's voice is awesome and how much Pablo Francisco is funny, I'm still voting for Morgan. Why? Cuz he's Morgan Freeman, duh.
Don't recall hearing Don's voice that much, but I probably have in some random commercials... However, Morgan Freeman's voice is so iconic and recognizable it's hard to miss him.
As an actor, Morgan Freeman would win in a landslide. However...
Based on their voices alone,
I had to think about what March of the Penguins would be like if Don Lafontaine narrated it in his signature style. That was enough to sway me. Morgan has a legendary voice, but Don is a master of suspense.
Morgan Freeman wins! ``````````````````````````````````````````````````````````````` Next battle: Best science communicator / astrophysicist / cosmologist
Neil seems to have a sense of humor, at least. Carl's voice can get on your nerves after a while, and his presentation isn't exactly exciting. I'm voting for Neil because I like his personality better, and because of spaghettification.
