Khajiit each and every time. I don't know why. I just got a steam deck and started Skyrim after not playing a while and tried to select something else, but Khajiit was the only thing that seemed right.
I got tired of the stealth archer, so I am trying a mage. It's pretty fun. Hard, but fun.
I wish there was a better way to navigate the menus. Being a mage is SO time consuming honestly. As much as I try to give alteration a stronger shot, I almost always end up going full destro because the time it takes to buff up and attack vs just going nuts is kind of annoying.
My last character was an orc and I try to play a different race each playthrough. My favorite would be either khajit or agonian tho, I just like them more than the others.
I have a very hard time not going Breton. They're a jack of all trades and their magic resist is hard not to pick.
It also doesn't hurt that a lot of the other racials are pretty useless and most of the rest are easily replaceable. Kajit claw damage is a notable exception for unarmed playthroughs (though that also is pretty niche), and there's just... something about playing a Nord in Skyrim.
I seem to gravitate towards Breton, Bosmer, and Imperial. Did a Stormcloak run as a Nord that used restoration to fight off undead and sided with Dawnguard. I like to roleplay my characters so depends on back story too.
