Vocally, I think Morrison may be a teeny bit better, but Aaron Lazar is definitely the better actor. Plus, he's so sexy... that always helps.
Ok, my Aaron Lazar fangirl-ness aside, TLitP is truly a great show. Love to Me and Dividing Day alone are worth the money for the entire CD. It's really an example of what a Broadway show should be- a bunch of good, intergrated songs instead of a few great songs stuck in a crappy score. Besides Dividing Day and Love To Me, it's not quite listen to on the bus and rock out material, but it's still wonderful.
Cosette: Roses are red.
Marius: Violets are blue.
Eponine: You're so in love!
Marius: And so not with you.
