It probably depends on the person. I'm not sure I'd want to work with people who see it as a negative, unless you're applying for a position where a PhD is required. You could try rewording: "unfinished PhD" seems a bit harsh compared to say, "PhD studies (incomplete)." If you're asked to explain, just eschew any shame and be confident: "It wasn't a good fit for my life at the time, and after changing course I'm much happier. Nevertheless, it was a rewarding experience and I'd do it again." Something like that, if applicable. To me, someone who endeavors to attain a higher form of themselves and fails is much more valuable than someone who never tried in the first place.
