Crunch first, fluff second. And I don't often go in for nuanced cultural descriptions and mating habits; because I can change the fluff how I want, and when it comes to pleasure reading I'd rather curl up with a good novel.
Just in case... I don't read up races description as "pleasure reading" but as very much (potentially) useful material for adventures and campaign.
To say what I mean in a colourful way, I may say that when it comes to races, for me "crunch is fluff and fluff is crunch", because the really meaty & useful stuff for me is in the fluff, and the crunch is a way to mirror that in the mechanics. (note that this is different compared to monsters, the main purpose of which is for encounters, and in our case are rarely used for PCs)
And when it comes to races, which being designed with PCs in mind they are not usually designed as a bunch of numbers (and abilities) but rather as a bunch of modifiers, i.e. they are "templates", this actually means that I can very easily change the crunch how I want. Changing the fluff is something that a lot of people think is easier, but I disagree (having seen thousands of re-fluffed things, very few of which were original at all).
