2019-7-29  Fortune III yields a 120% increase in dropped items when used on coal, diamond, emerald, nether quartz and lapis lazuli. So it's better to mine these with Fortune III, since pulverizing usually increases the yield by 100% only. For redstone, only the maximum amount of drops is increased (up to +3), so it's definately better to silk touch it.
