I've used the Rainbow Gun to one-hit-kill The Destroyer once, I often use this on The Destroyer. I've never tried the Heat Ray on mech-bosses since it is only available post-Golem, I usually farm mech-bosses after Plantera, sometimes even before. I'd rather use Rainbow Gun than Heat Ray, Rainbow Gun can work as a sentry, I fire it and it does its thing, also very useful for The Old One's Army.
