Nomad for the first "I have no idea what I'm doing so I'll utterly fail to make the choices or get the outcomes I actually want" build lol.

Street Kid for the character I really want to play (a super stealthy pacifist hacker - no kill run.)

And then corpo for the "it's all about my personal profit, I'm a psychopath now" playthrough that I inevitably eventually play for fun in most games. :P
