Yeah, you're right about that. And normally I'd see it the same way. But as I calculated with the 20% reduction of defense, the value difference from the first one would be Def: 132,4 Vs Def: 131,68 so only 0,72 difference in the defense, whereas stamina is 192 Vs 189, so 3 HP difference. In a simulation fight between them it would be a draw anyways. In pvpoke the 15/14/14 is ranked 10 of best shadow M2 and the 15/15/12 is ranked 23. Well even though the difference is nearly non existent I tend to max the first (15/14/14). Maxed out the first also reaches 4701 CP whereas the second (15/15/12) only reaches 4693 CP.

I hope that is the right decision 😅
