It depends what you wanna do with your pokemon, which role will he fulfills
The 1st one has the hidden ability, but if you don't use drought/sunny day, it will be close to useless, and he has really low IVs in HP, compared to the 2nd one
And if you want a full spatk venusaur, then the 3rd one is better
Thanks! I use for PVP. But i never fight before so i don know which one is best for pvp.
