Even though things are slightly changing now, PV and Alize were two very different philosophies: PV was economy service for the most part (economy drinks, economy meals till recently, no lounge access) but a clearly nicer/more spatious seat, Alize was a slightly nicer seat (but originally not nearly the same as the PV seat) but significantly improved service.

@chang11 - drink service in PV is exactly the same as economy. Champagne is served as an aperitif before the main meal, and the number of bottles they charge on board for Y and PV is low enugh that there is generally little or no leftover after that. If there is, FAs will give you refills in the galley if you go and ask until it's gone. Wine is available with meals on all AF flights except domestic.
