Spoiler alert: Iowa mauls the Yamato from long range with accurate gunfire. Battle is over within less than an hour. The US ships were faster, and their advanced radar and fire control systems gave them a huge advantage in naval gunnery.
The Yamato was a formidable warship, but it relied on outdated and flawed technology, and while it was more conventionally powerful than the Iowa class battleship, it was generally less effective. It's guns were only marginally more powerful, but had hugely inferior accuracy at range. It's armor, although thick, was of much lower quality, and it's torpedo protection in particular was weak for such a large ship due to poor quality construction. The Iowa had some of the best anti aircraft defenses in the world at the time, and while the Yamato did have a large number of AA guns, they were less effective than the Iowa's guns.
The Yamato's main advantage is it's stronger armor. It is, despite it's shoddy (by comparison) construction, a very large, heavily armored and durable warship that could survive powerful weapons fire for an extended period of time. However, durability alone would not be enough to carry the day against such a technologically superior opponent under most circumstances. Luck, crew experience and any supporting fleets would play a significant role, but the Iowa was simply a better equipped ship overall, and in a one on one engagement (or in a fleet setting,) the Iowa is the superior ship in most respects.
