I really like my male SI's voice.
The constant sneering goes well with his whole persona, I think. The female one is brilliant as well, though.
I really disagree about the SW! I adore my female SW - she's a... "large ham" (TV Tropes link.)
. Everything she says sounds so... grandiose. "I think it's time for a bloodbath!" "The Republic truly fears me!"
She's fantastic. But I can see how that might not be everyone's cup of tea. The male voice sounded a bit too stereotypical for my liking.
I think I like both VA's for the IA equally. They both do a great job.
I wanted to roll a male Bh, but I don't much like his voice/the way he says his lines. He's not a bad voice actor, just not really how I would have liked him to be.
