Minato was just as talented as tobirama with sensing. You can find that online.

It was stated that Minato was one of the greatest sensors that has ever lived im pretty sure.

Na im comparing how they both got their power, kaguya ate the chakra fruit and got insta op while the mc is basically the same his power is making him overconfidant and neglecting skill for power in my opinion.

Ehhhh not really, he’s turning more into kaguya really Basically he might have that strength but he has no experience in how to use that strength. The same thing happened with kaguya basically they both only know how to use their overwhelming power to subdue oppenents and no subtlety at all. So even though he has kage level body stats and extreme chakra an experienced chunnin and or jounin could still kill him. In my opinion thats the mc right now. Now the whole thing with the love interest already exposed same thing happened in Naruto with Hinata but the writers used Hinata and Narutos love story as kind of comedic relief throughout the manga and anime. This is just my opinion, in fact i think for his first fanfic hes doing quite well.
