In all seriousness, can we just say that they're both important? There's no need to compare two radically different shows..."
This is what I believe as well. They are both significant pieces in terms of expanding the form. They do so in their own way however.
Comparing these two specific shows to each other seems limited to me. I think there is a larger discussion to be had as to their influence on musical theater in general though.
StageStar, thanks for getting my humor and taking it in the spirit which it was meant.
You're a sweetheart.
