I like Lindor the most personally. Him trying to hit a lot of HR's this year while sacrificing average isn't the best use of his offensive skill set but his defense is the best of Correa and Seager who I think round out the top 3.
I think Correa has the most offensive potential of anybody listed but Lindor on defense is special.
Simmons is the best defender but this has been by far his best offensive year.
