Absolutely Jen Garner would win. She does her own stunts and her own fights. Jessica, though I loved Max and Dark Angel, used her stunt doubles and others more often then not. Jen has weapons training, Jessica not so much.
If we were going by fictional Syd vs. Max......I think Syd would still win, she knows how to fight with anything to win. To fight dirty if she has to.
^Max also knows how to fight dirty! *remembers the episode where she fights her clone and the clone tells her she's better because she hd more training, but Max replies "Yeah but they didn't teach to fight dirty" and then she fights dirty!* Whoa that was a long memory... Plus, Max lives in a dirtier world!!
Haha, yeah I think Jen would beat Jessica which is a question I've pondered before because I used to be more obsessed with Dark Angel than Alias, actually it was: Obsessed with DA, cancellation of DA, obsessed with Alias. Syd and Max on the other hand, I'm kinda confident Max would win! Let's see she spent her early childhood as a soldier, and she's got that super strength/hearing/speed/sight...etc.
But if I think even more about it, Max hates guns, Sydney uses guns. If Sydney has a gun and uses it before Max blurrs over to steal the gun and throw it away, she would win. ^_^
Man I so wanna watch a crossover between those two shows...
