I've tried PD a month ago and I find it mostly unpopulated with very little files, thus useless to the western leeching crowds. The listing font is awfully small and it can't be changed (for now). That's not really a big issue for me, but the small number of shared files is. One thing I like is that it finds results faster and isn't relying on trigger searches like in Share.
I obviously prefer Share at the current time but its memory leaks are freaking annoying. In any case, each of these programs lacks stuff. For Winny it's the security and viruses, for Share memory leaks, Perfect Dark is unpopulated and still lacking in features and design.
Oh, and if you want anonymity, just leech through a VPN network. Relakks does the trick.
