Would you rather be able to breathe underwater or be completely fireproof?

There are some caveats.
If you choose breathing underwater, you’ll be able to process oxygen through water, but your lung capacity isn’t increased. You can still run out of breath underwater if you over-exert yourself, but you should be fine as long as you stop and/or surface to catch your breath. If you want to improve your lung capacity, you’re going to have to commit to an aerobic exercise routine just like any normal person.

If you choose being fireproof, if only applies to your body. If you’re exposed to a big fire for a long time, your clothes are going to burn off at some point, and anything you’re carrying on you is probably going to get destroyed.

I'd rather breathe fire and be completely waterproof.

How would bathing work if you were waterproof? Assuming your skin takes on the qualities of an aquatic creature, bathing may become a non-necessity. However, in the opposite case, would the oils and sweat of human skin become trapped between the waterproof barrier thus rendering you unwashable?
