Gogo from Kill Bill
or
Miho from Sin City
Be sure you’re specifying whether you’re talking about which one would win in a fight, or which one you would rather do.
“Deadly little Miho” on both counts.
Miho is way more attractive.
Gogo. She’s got a schoolgirl outfit. Something about Miho tells me she plays for the other team anyway.
Miho would eviscerate Gogo in a fight, and is way hotter.
The correct answer, as always in these “hot girl X VS. hot girl Y” threads, is both. 
As for who would win in a fight: who cares as long as I can watch!
hehe. I opened this thread thinking it was about blues artist David Gogo.
As to the OP, I would enjoy spending an evening with either young lady.
(I am a girl. And straight. But I can still play. Just a warning.)
I like schoolgirl outfits but I think Miho would kick Gogo’s ass and is hotter.
Edited to say: BTW, thanks for the links. It really helps refresh the memory, otherwise you’re left thinking “I watched each of those once, I vaguely remember, but not clearly enough to answer…”
As long as you treated her OK, Miho would probably be cool with you. Gogo would kill you just 'cause she didn’t like your shirt. Because I like being alive I’d rather spend time with Miho.
Like most of Miller’s characters, Miho is overblown to the point of absurdity and has powers and skills no one could actually attain, so she’d probably win in a fight. Also her weapon is more practical.
And, honestly, if you really get the urge to see Miho in a schoolgirl outfit, you can just rent DEBS.
I had never heard of that movie, but the Plot Keywords suggest it may be worth a look.
It’s…oddly watchable, in an inexplicable train wreck kind of way. I found myself enjoying it quite a bit more than I thought I would, but I wouldn’t call it a good movie.
But still. Devon Aoki in a schoolgirl outfit, can’t beat that.
You’re all wrong. The answer for most deadly and most bang-able is O-ren Ishii.
陰茎がばくだんするほどおれんいしいとセクスをしたいなぁ。(Inkei ga bakudan suru hodo O-ren Ishii to sekusu wo shitai) Translation: I want to fuck her until my penis explodes. 
In a fight: Miho.
Hotness: Gogo.
I like Gogo’s personality better, in that she has a personality. Miho is cute, but looks a bit odd. And like Grossbottom said, I don’t think she’s actually into guys.
(Side issue: Devon Aoki, in real life, strikes me as having about 5 brain cells. If that. Chiaki Kuriyama is definitely more intelligent. I’ve seen interviews she’s done, and a buddy of mine got to see her live in a panel discussion.)
