Yes, ASSASSINS is an ensemble piece...that's why he won best supporting actor. I didn't care for O'Hare, I thought he was unnecessarily over the top and too (forgive me) feminine.
While Raul sounded amazing singing "Petrified," nothign can top the emotion and brilliance that Cerveris had in ASSASSINS. And, in my opinion, Esparza is FAR better than Paul Baker any day.
