Unfortunately, I don't know much about Blacks. I've had the opportunity to play with Cream Dampened, White SKCM and White SKFM, Orange, and Green Alps, all of them between 20 and 25 years old. I enjoyed typing on all of them, but not before cleaning!
Orange are by far my favourite. I can say, however, that the first orange board I had needed extensive cleaning, and felt terrible to type on before I got around to opening up each and every switch to clean them. It makes a HUGE difference. So don't judge a dirty switch. That said, Blacks may not be for you! I'd start by opening a few, cleaning them, and type in that cluster to judge.
EDIT: If you still don't like them after cleaning, let me know! I'm curious about blacks and would love the opportunity to try them out!
