The Lenovo Legion Slim 7 has a better screen than the HP Omen 15 for general use, gaming and AI, and engineering and design.
For general use, both the HP Omen 15 and Lenovo Legion Slim 7 offer screens with adequate resolution, brightness, and the appropriate panel type to ensure crisp images and comfortable viewing. When it comes to engineering and design work, both models provide good color accuracy and a range of colors, making them suitable for detailed and color-sensitive tasks. However, for gaming and 3D applications, their refresh rates may not be high enough to avoid motion blur or provide the smoothest visuals, which is less ideal for fast-paced or highly dynamic content.

Florian Glaser | January 2021
"We consider around 1,260 Euros (~$1530) for a Ryzen 7 4800H, a GeForce RTX 2060, a 512 GB SSD and 16 GB dual-channel RAM to be a good offer that appeals to price-conscious gamers. Very high details are rarely a problem in the native resolution of 1,920 x 1,080. Buyers will also be spoiled with a top-notch battery life that even beats most other notebook classes. If HP now improves the speed of the WLAN module, the stability of the case and the repeatedly criticized picture quality, the competition will have to dress extra warmly."

"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
