Teanna
That depends. Miko Lee is all hardcore like a tank of action where Teanna Kai is more subtle. It's like comparing driving a Hummer to a Ferrari & ultimately who you'd prefer tells a lot about your character.
I'd do both but it'd depend on the mood I'm in, that is, who I'd prefer given a time here and there. Miko's good for 'just getting down to it' & a rough wild ride at that, where Teanna is more about taking easy & longer & experimenting rather than getting right to it.
