False. Det is literally only a few percent difference. It will save no GCD casts.

That one run in 1000 where a player survived a raidwide with double digit health after you healed them is where Det helped. DH would help in that one run in 1000 where you wiped at sub 1%. Pick whichever helps you sleep at night, it's irrelevant.
