That question is a long debate which still hasn't reached its conclusion, but here's what I think it comes down to:

PD on Yi is very good. A Youmuu's Ghostblade's normal buffs aren't as good as a PD's. Hitting a Ghostblade's active makes it better than the PD for the duration of the buff.

So, the answer to that question is a question of time (and remembering to activate the ghostblade): How much time do you spend in fights, and how reliable do you want the bonus? If the duration of the ghostblade buff is less than the time you're dealing blows in a fight, go ghostblade. If you spend more time fighting or don't like the fact that you're less combat-effective while the ghostblade is on cooldown, go phantom dancer.

All depends on your play style and confidence really. I'd recommend a PD until you're comfortable in your Yi play style, and then going ghostblade and seeing if it helps or hinders your game. If it helps, use it in the future. If it hurts, switch back. If you own/suck just as hard with it as with PD, pick one arbitrarily (flip a coin or something).
