Unfortuately I did smoke both a lot more than once (in terms of bowls, not packages), but fortunately it was a long time ago and I had already been smoking good quality blends so neither of them clouded my appreciation of pipe smoking. CH allegedly contains a small amount of VA, whereas PA allegedly contains some cavendish, but both are, like most OTCs, primarily burley, and not the top-grade stuff either. Both are topped with a variety of flavoring syrups. They differ a lot in tin-note, somewhat in room note, and very little in taste...which might be due to the fact they have very little taste other than the cheap burley, which some like but I don't. For the price of a tub of either one, you could get a smaller tin of any one of hundreds of good-quality blends. Some people swear by these venerable drugstore everyman blends, I swear at them. YMMV.
