Explosions are not appreciably different from one another. Your senses probably aren’t good enough to discern the slightly greater strength of the soft-tissue destroying shock wave that makes the excited bang, or the exciting new toxic chemical cloud they’re dispersing.
I’m not a great chemist, but the reaction products from FOOF aren’t very pleasant looking either, from a being-a-carbon-based-lifeform perspective. Fluorine is a nasty oxidizer by itself; I can’t really imagine anything pleasant happening messing with a chemical that involves an -OF group.
Hydrofluoric acid is a bitch. Worked with it once — once! — in college. Never again.
