Wow, same moves.
If they had the same Attack stat, I would choose the one with the higher defense, for Entei is health-based and has lower defense, so defense would help it use all of its high health instead of add a tiny bit more health with Stamina.
Then again, one of these is 15 attack and another is 14, and their moves and IVs are similar.
I would go with the 15 attack one.
