Young Danzo seemed hot-headed and eager to prove himself. Reckless, more like Naruto if you ask me. He also is also pretty ruthless compared to Sauce, as he was even willing to have Hiruzen assassinated. Danzo fully supported the shinobi and village system, and the idea of ninja above all else. Danzo is very draconian, amoral and self-righteous. He has no sense of nobility or dignity. He supported Konoha up until the end.
Let's compare that to Sasuke, who has always beem cool, calm and collected. Overly self confident. He's always been about his own goals and his clan, much more than the village. He is only protecting the village because that's what Itachi wanted. In the end, Sasuke hates the idea of the ninja system, and wants to abolish it
That is totally different than Danzo. If anything Naruto's mindless support of Konoha borders on fanaticism and would lead to more wars. In short, Naruto is more like Danzo. Also, I'd argue Naruto would be a horrible Hokage and is too unintelligent and immature to be an effective leader.
