There really is no comparison... They're different singers who both have incredible voices, so to be trying to put Charice down just because her live, spur of the moment freestyle from Burlesque wasn't the same quality as Christina's studio version from the movie is a bit heartless... They both deserve respect and both have incredible voices. They can both do things other people only dream of doing with their voices. This whole "I can only like one artist and if others try to sing I'll hate on them" business is getting old.
