The HP Omen 15 is often a bit less expensive and is geared towards gaming with a robust build that can handle heat well. However, it's heavier and has a lower resolution and refresh rate compared to the Lenovo Legion Slim 7, which is more portable with a higher resolution and refresh rate, making it suitable for creative professionals and those who appreciate a more vibrant display. While the Omen 15 has an older GPU, the Legion’s newer GPU provides better performance for 3D and machine learning tasks, and it also has a longer battery life, more modern ports, and additional features like a fingerprint reader. If you prioritize gaming and want a more budget-friendly option, the Omen might suit you, but if you prefer a lighter laptop with a better screen and longer battery life for varied intensive tasks, the Legion Slim 7 may be the better choice.

The Lenovo Legion Slim 7 has a better screen than the HP Omen 15 for general use, gaming and AI, engineering and design, content creation, and software development.
The HP Omen 15 and Lenovo Legion Slim 7 offer panels with sufficient resolution and brightness for daily tasks, making them suitable for general use. For engineering and design, both laptops have displays with a wide range of colors, but they may fall short for professional color work without full coverage of DCI-P3 and Adobe RGB color spaces. Gamers and 3D artists, however, might find the lower refresh rates limiting, as these can hinder the smooth visual experience that's crucial for fast-paced games and fluid 3D rendering.

How the HP Omen 15 and the Lenovo Legion Slim 7 16" compare to other laptops
"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."
