This is what people fail to get, when they look at the surface of things.
Both plans by minato and itachi was a gamble. The only reason why people believe minato's was better is because its paying off and itachi's isnt.
Naruto couldve easily let hate consumed him a couple of times and couldve been like gaara in part1. Similarly if itachi's gamble paid off and minato's didnt people would say itachi's gamble was better.
Anyway i believe in the end sasuke would become a good guy and along with naruto will defeat who ever the final villain turns out to be, so for now you can say itachi's plan is off the rail. But once sasuke's turns good again, his plan would turn out to be a success
