i say it smells like neither. Powdered PCP is rare and not common, at least in my experiences....
the smell, at least to me, is like what heaven would smell like if it was chemically recreated...no, I wouldnt say ether. Though, def. a chemical smell (and strong at that, often, we would have to keep outside the car in the side view mirrors, though I dont suppose that many cops could describe it either...).
Often, it is packaged with speariment leaves, so sometimes you can catch a wiff of that combination. However, must common is either premixed (in stamp bags) or liquid (usually in unmarked, small glass containers). The only way to know is to take one puff. One puff, to a new-to-PCP user will give them a definite feeling that they are getting what they paid for.
btw, back in the 80s, I had the fortune of smoking some red devil from 14X street (no sources, anywhere up here is bad news). damn.
Oh, my opinion, prepackaged bags beat dip nine times out of ten for the reason it is easier to control dosing. Dips have the tendency to have smokers overdo it....and trust me, if you have a jug of some diesel, you WILL overdo it. At least with bags, you can gauge your high and work to match, meet, or slightly overachieve. Anything more can be disastrous, or at least lead to some crazy stories for your grandchildren.
Sweet dust.
