My GPA is an occasional SPS, and mostly LPS nipper, has destroyed some nice blastos and ehino's in the past, but it is also my favorite fish. I thought about selling it once, but couldn't bring myself to go through with it, I've had her going on 4 years now.
This would make a great fish for someone with a softie dominated tank (but no agressive tank mates). They get less shy as time passes, as long as there are no aggressive tank mates. If you've ever wanted one it's best to buy one that's been in captivity for awhile (a year is a good indicator) to ensure it's healthy; they're frequently cyanide caught.
