First of all, I think Pure Coffee is a little overrated. I really like my coffee to be a latte or cappuccino with frothed milk, vanilla chocolate, etc. I kind of just get an ordinary "drip coffee" scent from PC.
As far as PM and PH, it's very hard to choose, and I won't at the moment. PM is more masculine, PH is more gourmand. I used to occasionally get a rubber note in Pure Malt, (somewhere in the midnotes) but don't seem to get it anymore.
