It skis in the pow like any other stiff park ski..
And I personally didn't like them at all mounted anywhere ahead of -5 of true, and at -6(reco.) they skied and carved pretty well, but I only cared about park performance, and since I like my park skis mounted at about -2 I didn't keep them.  If you would mount back and use them for a do it all ski at a resort with mostly hard conditions they would do good at that.
Somebody who owned P3s that I let try my Chronics(I was on my other skis so didn't try the P3s) last year said he liked his P3s way more, and they seem to have pretty good reviews.
As far as normal sidecut normal camber park skis, my favorite so far has been Pipe Cleaners, which carve and ski switch better than any other park ski I've used (mounted at -2.5).
