That's a defensible take. Vaporeon has 130 HP, 110 Special Attack, 95 Special Defense, and a 525 base-stat total. Water Absorb also gives it an immunity to Water attacks, making it useful as a bulky special attacker. Its 65 Speed and 60 Defense hold it back, though, so whether it's the “best” depends heavily on the game and role you're considering.
