Holliday was a force of nature on stage. I would venture to say her sheer power and vocal energy can never be topped. She can't even get to that level herself anymore. She was 21 back then, and heavier, and both helped her to explode with the unmatchable excitement of "And I'm Tellin' You." It was as if she was self-destructing in front of you. Tearing out her voice like that, every time. It worked in a HUGE way, but it also took its toll on her.
Hudson is fantastic on that song too, but she doesn't reach Holliday's power. Close! But no cigar. She doesn't push off the deep end into self-destruction.
However, Hudson gets my vote OVERALL, because her acting is much better than Holliday's ever was. Later in Holliday's run you even got the sense that she was almost "marking" the show to save herself for "And I'm Telling You" and "I Am Changing." She kinda walked through the rest of it, a bit. And it's understandable. She was like an athlete pacing herself for the triple somersault.
Hudson's work is on film, and I don't think she could do any better sustaining Effie on stage than Holliday did, plus she already can't deliver the song with THAT much power (nobody can). She had multiple takes, and didn't have to worry about pacing herself for the rest of the show. So I'm already "discounting" my choice...
But since I'm basing my ultimate decision on the impact of the entire performance, I'm picking Hudson (qualifiers and all).
