I have used both maxed 5/30 and here is what i found. Diaz when he first dropped wasnt as good as the stats say he should be so i bought Vini dropped Diaz to bench because iclaimed him with shards. I got sick of Vini getting bullied and fouled with no calls, sold him tried various players 112 Kvara, new Leao, etc you get it lol. I said let me try this Diaz again he has to be expensive for a reason right. They clearly fixed the card in game now and plays like the stats say he should. Vinis is better speed wise overall and skill moves, but Diaz is stronger, better shot, and better passing in game. Diaz dribbling and pace are among the best though. IF you have 1 untradeable i wouldnt waste coins on the other, but if you use coins on them try both.

They improved this card he feels like a new player and closer to his stats.
