In 2minutes, Minato was able to notice Tobi wasn't Madara. In decades Itachi never knew Tobi wasn't Madara despite the guy having being his mentor for quite some time. In fact, he got fooled by the guy so badly that Tobi knew almost everything concerning Itachi without him even noticing. Minato has shown a similar capacity if not greater than Itachi when he was able to read through Bee's heart just after seeing him once, knowing the real reason behind his strength, something that A only noticed decades after during this war, he knew Tobi would be the cause of disaster after observing him, like he predicted Naruto would be the one to save the world. Minato actually despite being much less present in this manga than Itachi, has shown greater feats in terms of insight abilities or seeing through people. Minato managed to hit Tobi which few people have done and formed a quick plan he was also able to analyze Kakashi's chidori in a matter of seconds and tell him his flaws of it.
Obito has intelligence feats that surpasses Itachi's in my opinion, one of the smartest guys in the series as far as analytical, strategical, and planning abilities go. A real genius Madara trained him well. He not only used a bunch of power-house freaks but also deceived most of them into thinking he was a newbie to the organization and ultimately hid his real plan from them all. He controlled the Mizukage for years with his genjutsu. Foresaw Itachi dying, fooled and knew everything concerning him to the very end. Every time Naruto and co. threw a wrench into his plans, he would look at zetsu and say onto plan B, he always had a backup plan when things went wrong. He didn't even need Madara to go through with Infinite Tsukuyomi. Obito knew everything about the Uchiha clan secrets, techniques & everything about the shonibi world. But most people overlook all of that.
While Itachi is very smart, too many people over-exaggerate his capabilities. If he was really that discerning, he wouldn't have gotten manipulated so bad, and misjudge Sasuke by a mile. Now I'm not bashing Itachi, he is a good character, but rarely do I run into anyone here that can look at him objectively.
