Benzema is definitely way superior to Dzeko (a more complete footballer, even though he is not an out and out striker); RVP and Falcao as well.
Benzema isn't even the same type of striker as those guys, so I don't even know why he is on the list. All those guys are more or less prima puntas, whereas Benzema is more like a Rooney/Tevez/Aguero.
