Build quality is excellent between all three models. If we had to choose one, then it would be a close toss-up between the G751 and Alienware 17 R2. The G751 utilizes thick hard plastic, brushed aluminum, and soft-touch finishing to separate itself from the outgoing G750 models. While these are nice visual touches, they ultimately do not significantly improve build quality compared to its predecessor. The large base is already very sturdy and is superb as-is, but the lid is of only average rigidity in comparison.

Meanwhile, the Alienware is shinier and brighter with numerous LED effects. Its hard plastic base is as tough as the Asus, but its hinges and matte aluminum lid are both stiffer in comparison to give the model the edge.

Lastly, MSI should be given an award for most improved design for its jump from the outdated GT70 to the newer GT72. The matte finish and brushed metal surfaces rival both Asus and Alienware. Unfortunately, its hinges creak and the display will squeak when twisting, so there is still room for improvement. Additionally, the metallic surfaces attract fingerprints much more easily.

If based on pure size and dimensions, then Alienware comes out on top for being much thinner and lighter. The G750 and G751 are notorious for their thicknesses and weight and can be up to half a kilogram heavier than the Alienware or MSI. In Asus' defense, however, this does have a positive impact on performance. Alienware still wins this round for its smaller size without sacrificing rigidity.

The design philosophy behind each model is uniquely different. Asus has drawn inspirations from jet fighters for its ROG designs, while Alienware targets a more futuristic appearance with flashing lights. MSI designs are less dazzling and prioritizes form over any extrovert features. It's ultimately a matter of user tastes in this regard.

Winner: Dell Alienware 17 R2
