I'll pick Snivy in my white version. Just because I like the last form of that Pokémon.
And there's another reason. I wanted to choose Snivy or Oshawott in my japanese black version. I chose Oshawott. So now I want to see the adventure with Snivy.
Oshawott is a good choice too. I learned him TM (like surf and cascade).
I don't like Tepig final form... So it is why I don't hesitate between Snivy and Tepig
