Both of them are really great...I like Nidoran F becuase it's cute, and I like Nidoran M because it evolves into Nidorino - which is really cool, IMO. ^^
Nidoran(Male) is better. Because after it evolves into Nidorino then to Nidoking with a Moon Stone, it will be much stronger with its attacks like Poison or more..... Nidoran(Male) rocks!
They're both good, but I like Nido F better. My level 32 Nidoqueen was the Pokemon that defeated Lance's strongest Dragonite in my Silver game. So perhaps I just consider it one of my lucky Pokemon.
