How the HP Spectre x360 and the MSI Stealth GS66 compare to other laptops
"As we said, Lenovo's Yoga 9i is a tough competitor to the Spectre with an equally admirable OLED display. We're sad that neither of them has an HDMI port nor a niche or slot to hold the stylus, though the HP wins points for its bundled mini docking station and magnetically attached pen. Your choice will come down to screen shape—and in our eyes, just as seeing an OLED screen spoils you for an IPS panel, enjoying a tall 3:2 display spoils you for a more conventional view. The HP Spectre x360 13.5 is our new favorite 2-in-1."
"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."
