Frank Welker is good, but come on, comparing him to Mel Blanc is like comparing Letterman to Carson (Johnny, not Daly). Mel Blanc was the original, and he will probably never be surpassed, if only because there are so many more voice actors now than there were in Blanc's day. He was doing every voice in the cartoons; nowadays, you've got a full cast for any animated show. There are some brilliant voice actors out there; Billy West, John DiMaggio, Hank Azaria, Harry Shearer, Dan Castellaneta, Seth MacFarlane, Alex Borstein, Patrick Warburton (he only does one voice, but he does it so damn well), Maurice LaMarche, Frank Welker, Sterling Holloway, Tress MacNeille, James Urbaniak, Peter Cullen, Jim Cummings, and like 50 more.... And none of them will ever be as good as Mel Blanc. But that's ok; they don't need to be. They're all great in their own right.
