I found PMC to be a creamier lemon scent than PM which was a more raw lemon in the top. I bought PM because I liked the scent more, I only wish it lasted longer, the longest I've had it stay on me was probably 3-4 hours.
For the record mine is the "new" one with the greenish colored juice.
From my, pending, review on Pour Monsieur:
"I equate this fragrance to speed dating with a supermodel. Fun as hell, but it doesn't last for long so make it count!"
I think that pretty much sums it up.
