I do like 6we's idea of letting you do well at just about anything with any metatype, without struggling. I'm glad you can be an ork face or troll technomancer, because, hey! More options! Also, I've sometimes felt that dwarves tended to get under-represented, so now there's more incentive to pick them.
But if the good reason to be human is underwhelming, it might end up leading to an idea of "Humans are boring". Plus, considering the Sixth World is a bit more welcoming, "metas stand out" shouldn't always hold true, depending on where you are and who's around.
Though talking about shadowrunners here, being a dwarf or ork probably won't make you stand out as much as carrying around a Vindicator on a bipod, or having a great big spirit following you around while you've got a half-dozen spells on you.
