Minato easily.
How come?
Took him few seconds to figure out Obito's ability. While it took others hours.
Thats 1 person and 1 intellectual feat... Itachi has many
They maybe equal in battle intellect had minato lived a while longer in the series.
Both were held as best of prodigies and look at kakashi who was trained by minato himself his battle intellect is second to only itachi.
So yeah minato = itachi in battle intellect.
Quality over quantity.
Itachi defied Edo Tensei while minato was still stuck in it only was free due to oro deciding ti follow sasuke's orders
I give it to Minato. Figuring out Obito's ability in the situation he was in was incredible.
Yeah keep speaking. Quality over quantity.
Well Minato got better grades in the Academy according to Itachi novel
As for battle tactics I would place them as equals.
That was a show of levels, both were Edo summons but only one could be free while the other stayed a pawn... #Levels
