Not so much with the technopathy. I wouldn't put it past her, but she just creates the tech herself.
Think of her as a low-level GL, but with metallic nanobot constructs instead of light-based constructs, and a considerably higher IQ than even the most creative GLs.
In terms of versatility. She's insanely brilliant, and has some awesome on-the-spot tech to her credit. But she lacks the raw power of a GL. A good GL could just blast her to the moon and kill her.
I'm pretty sure it's a Diana stomp if she fights serious. Angie's main offense is gun, pretty much useless, Diana's *way* faster and stronger and can KO her (and any duplicates) quite quickly, the bugzapper feature on her bracers can fry nanos and other machines around her, and The Engineer doesn't really have a good defense against being punched out by a foe this level.
She's got the flexibility of a GL or more-so, but not the power.
I think that it is feasible for Angie to take on Diana, my doubt was about staying power, speed and the status of the physical match. Certainly Wonderwoman is no Superman and she is not nearly as good with her physical powerset.
Uhhh... guess you haven't read much Superman or Wonder Woman for the past, I don't know... decade or two...
WW doesn't have the *accessory* physical powers that Superman does (Heat Vision, Super/Chilled Breath, superior Invulnerablity), but in terms of simple physical power, she is his near equal (He is stronger and more resistant; she is faster in HtH combat and has greater finesse when fighting). Given that she is almost as strong as SM, is a better fighter, and is capable of withstanding much greater physical punishment than most people realize (as of the past 10 years+), your assessment is very skewed.

With that said, Angie has a couple wins going for her, given the nature of her abilities, and the possibility of using some highly finessed/techniqued applications of her powers to win against Diana, but overall Diana is taking the clear majority of wins here; Diana can (and has) stood up against GL's and won (including the likes of Sinestro), and as others have stated, Angie doesn't have the raw power backing her abilities that mid-to-higher level GL's have (though I wouldn't underestimate Engineer and call this a slam, by any means -- like I said, she can get at least a couple wins with finesse and/or surprise).
__________________ Why am I here commenting on this crap?
The difference in power level between Superman and Wonder Woman is essentially academic unless the foe is at *least* in the mid herald class. They'll both just beat down anyone less than that with ease, at least when it comes to power-to-power.
Lesse... the first 4-5 trades plus both Revolution books and Captain Atom: Armageddon.
Yes, she has a lot more tricks, but her first go-to is still making big chaingun arms.
In a less strait-up fight she'd have a reasonable chance of getting a stealth win with her nanos, and she can likely finesse the odd win, but she's outmatched here.
