Both figures are done rather well, but in comparison I'd say the Legacy one is better. It may be a bit too tall, but the face sculpt is magnificent and the over all detail of the figure really shines. The DC Direct one is pretty good overall, but the head sculpt/paint is lacking and the articulation isn't too great. I do prefer the height/proportions of the DC Direct version, but the Legacy one is the obvious winner here.

i like both of them man but ur right the legacy has the better face sculpt though on ac i like the real metal chain

I know what you mean. A big highlight of my DC Direct Jokers is that they have the real chain, but they also have strong head sculpts and the face is really lacking on DCD Harley. I would have never expected that a DC Direct figure would look worse than a major retail figure, but honestly, the Legacy one is top notch and it is the one I'd recommend to anyone that wanted to pick up an Arkham City Harley Quinn for their collection. By the way, I haven't completely turned my back on the DCD Harley, I ended up giving it to my little sister because she likes the character design and the game.

Yep, i'd definitely say the Legacy version too. Easily one of my favorite female figures ever, her artuiculation is just about perfect and is hidden amazingly, making one badass figure. Mattel seriously knocked it out of the park with ol' Harley here.
...but
....with her being so great it does make one wonder
...WHAT THE FUCK happened with AC Robin?!
...was it an "off day at the factory or something? (No ab-crunch REALLY?)
