It is far above the average naruto fanfiction, but still nothing impressive. There are quite a few better than this, but it far outshines the average ones. The writing quality is average, but the story makes up for it a bit. There are some grammatic issues, weird phrasing, awkward descriptions and the like, but it is still readable. The world background is developed a bit, but is still lacking. There are some issues with logic and inconsistency, as well as the lack of understanding the world. Some earth shaking changes made in the story have ZERO effect on the world. For example, Minato learned the Flying Raijin in less than a year. If it was so easy to master, the world would've been different. And this is just one of many. THE PLOT is ok, nothing spectacular, but has some original points. Characters are decent, but still have a lot of issues. The author somehow thinks that behaviour is genetic? WHAT? (Example with shisui) And ignores most of the changes the MC's presence would bring to the people. And now for the MC. He does actually think a bit, but not that much. He doesn't use his knowledge to his full advantage and just stays in Konoha being content. With his power, he could transform the world in years, create ways to grow at insane speeds, raise children to be powerhouses, revolutionize the education system, bring out new reforms, improve the lives of all, unite the world under one banner and so so so so so much more. Yet he stays in Konoha doing nothing. I know this is partly because of Madara, but it is still a bad excuse for lazy writing. The MC was stronger than Madara long ago, yet he for whatever reason persists his stupidity.
