The Lenovo Legion Slim 7 15.6" is good for gaming and AI, while the LG Gram 17 is only fair.
The Lenovo Legion Slim 7 15.6" is equipped with a powerful Nvidia RTX 3060 GPU and a high screen refresh rate of 165Hz, making it well-suited for gaming and 3D applications.

Although they have very similar scores, PerfectRec considers LG Gram 17 to be very good for engineering and design, while the Lenovo Legion Slim 7 15.6" is good.
The Lenovo Legion Slim 7, with its AMD Ryzen 7 CPU and Nvidia RTX GPU is well-suited for engineering and design due to its strong performance in processing and graphics, although it is less portable and noisier compared to the LG Gram 17. The LG Gram 17, which balances a capable Intel CPU with an Iris Xe GPU and a high-resolution, larger screen, offers exceptional portability and a quieter operation, making it an attractive option despite its less powerful graphics.

Benjamin Herzig | November 2022
"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."

"The LG Gram 17 is a light office laptop with a large display and great battery life. The newest incarnation of the Gram 17 can be classified as a model update. LG uses the predecessor's compact, light magnesium case along with an identical port configuration (including 2x Thunderbolt 4) and keyboard. Changes can be found in the hardware. With the Gram 17 (2022), LG offers a light (approx. 1,350 g), mobile work device - and finally with a matte display."
