Achillobator giganticus v Dilophosaurus wetherilli
Achillobator giganticus
Achillobator (pronounced /əˌkɪlɵˈbeɪtɔr/; "Achilles' warrior/hero") is a genus of dromaeosaurid theropod dinosaur from the late Cretaceous Period of what is now Mongolia, about 90 million years ago. It was probably an active bipedal predator, hunting with the large sickle-shaped claw on the second toe of each hind foot. It was a large dromaeosaurid: the holotype and only known individual of Achillobator is estimated as 5 meters (16 ft) long. The fossil remains of Achillobator were first discovered during a Mongolian and Russian field expedition in 1989, though it was not described and named until ten years later, in 1999, by Mongolian paleontologist Altangerel Perle, and Americans Mark Norell and Jim Clark, although the description was not complete and was actually published without the knowledge of the latter two authors. Estimates suggest that Achillobator weighed 350 kilograms (771.6 pounds) at most.

Dilophosaurus wetherilli
Dilophosaurus (play /daɪˌlɒfɵˈsɔrəs/ dy-lof-o-sawr-əs or /daɪˌloʊfɵˈsɔrəs/; Greek: di for "two", lophos "crest", and sauros "lizard") was a theropod dinosaur from the Sinemurian stage of the Early Jurassic Period, about 193 million years ago. The first specimens were described in 1954, but it was not until over a decade later that the genus received its current name. The largest known specimen weighed about 400 kilograms (880 lb), measured about 7 meters (23 ft) in length, and its skull was 590 millimeters (1.94 ft) long. The smaller holotype specimen weighed about 283 kilograms (624 lb), was 6.03 meters (19.8 ft) long, with a hip height of about 1.36 meters (4.5 ft), and its skull was 523 millimeters (1.716 ft) long. The most distinctive characteristic of Dilophosaurus is the pair of rounded crests on its skull, possibly used for display. Studies by Robert Gay show no indication that sexual dimorphism was present in the skeleton of Dilophosaurus, but says nothing about crest variation. The teeth of Dilophosaurus are long, but have a fairly small base and expand basally. Another skull feature was a notch behind the first row of teeth, giving Dilophosaurus an almost crocodile-like appearance, similar to the putatively piscivorous spinosaurid dinosaurs. This "notch" existed by virtue of a weak connection between the premaxillary and maxillary bones of the skull. This conformation led to the early hypothesis that Dilophosaurus scavenged off dead carcasses, with the front teeth being too weak to bring down and hold large prey.

Dilophosaurus is bigger, but they are pretty much equal in every other category. So it gets my vote.

Wouldnt Achillobator hold an advantage interms of claws?

Yea, it probably does.
Dilophosaurus was larger, but it's behavior would not make it a good fighter. Though, Achillobator also was quite heavy, so it wouldn't be able to make very large leaps. The outcome of the fight would depend on the "battlefield" environment. In the dense forest dilophosaurus would most certainly win due to it's superior flexibility. Achillobator was one of those dromeosaurs with a very rigid tail that served for greater balance, so it would certainly give Achillobator an upper hand in the more open area, where it would outrun Dilo. I'm not totally sure who to back in this fight. My peraonal sympathy would of course go to Dilolphosaurus, but in reality both can win in certain situations.
