EDITOR'S OPINIONRight off the bat, Scott Menville is easily the worst voice in this compare. I know he was supposed to be a young version of Fred but it is just awful compared to Weinrib. So, Weinrib wins in the kid-version category.
Daws Butler is usually at the top of all my lists but I must say that I am glad this is one role he didn't get to keep. So it all boils down to Bergman who does a great impersonation of Corden and the original(s) Alan Reed and Henry Corden.
In the end my vote goes to Corden. 1: Corden, 2: Reed, 3: Bergman, 4: Weinrib, 5: Butler, 6: Menville
