Tin was far more scarce than iron. Iron weapons aren't any better than bronze ones, just easier to source and make. This guy makes a case that iron weapons caused the Bronze Age Collapse.

Don't confuse iron weapons with steel. Steel was much better than bronze, but they didn't know how to make steel and so examples were rare. (probably not unknown, making iron weapons does produce a small amount of steel and if you're careful you can separate that out and after a thousand or so iron swords you can make one steel sword. I've seen it suggested that this is where the stories of a legendary weapon comes from - probably not something we could ever know for sure.)

Bronze is harder and more corrosion resistant, but forged iron (and especially iron that has been reforged) has a higher yield strength and is lighter, allowing longer lighter weapons. Compare the profile of bronze age and iron age swords in any museum and you can see that the bronze blades are shorter and wider that the iron weapons, and they would be considerably heavier.
