Is the chain breastplate good in minecraft?

So the chain armor in minecraft has special features or something?

Nothing special. Iron is better

This is actually only for collecting because you can't make it, so if you find one you're in luck

You can only find fortresses in Nether, which is a bit worse than iron armor, I would say throw it away unless you collect them.

You can hang on an armor stand, but otherwise relatively useless
