"The 2023 Dell XPS 15 is more or less exactly what you'd expect from the company flagship. Its fresh components deliver measurably superior power and longevity, while the machine's premium build and design remain intact. It may not be overly exciting, but XPS loyalists and upgraders should be more than happy."

"The MSI Stealth GS66 is powerful enough for QHD. The Core i7-12700H and the GeForce RTX 3070 Ti found in the 12UGS model that we tested run all modern games smoothly in the native QHD resolution. The 15-inch display is very fast with its 240 Hz refresh rate, and it also offers a great color space (almost 100% DCI-P3) on top of that, which should please gamers as well as content creators, although we would have still wished for a higher brightness. Case, input devices, and connectivity (Thunderbolt 4) are at a good level. However, among other things, the GS66 loses points due to the high temperature development in 3D mode and its poor webcam."
