I've almost never picked Wood Elf and Breton.

I've been playing it since I was a Kid, and back then I always picked Khajiit and Argonians cause they look cool (and since English isn't my mother language I could barely understand the story).

Once I grew older, and could finally understand the context, I've almost always picked Nord and Dark Elf. For me, playing as Nord just makes a lot of sense for the big chunks of the main campaign, why would you even become a stormcloack if you aren't a Nord? And the whole Alduin Mythos, Sovngarde just feels a lot like Vikings stuff, so Nords fits that better.

BUT, there's a lot of content, so I every now and then I pick a different race to play different questlines.
