Clearly states DH slightly ahead WW. Also top 1% DHs have a tiny bit better average rating than the top 1% for WW. Or take Drustvar. When I combine both regions and look at top 500 in 3vs3, WW is the worst melee spec, behind DH.
Nearly same picture in Shuffle. While WW has more than double as many spots on 1800+, which speaks for a lot larger player base, this lead shrinks to 2 spots on 2400+.
But not worth it the energy to fight it out, which spec is exactly more trash. Buff boths!
