The ASUS TUF Gaming F15, being slightly more expensive, offers robust performance suited for intensive gaming and engineering tasks due to its stronger GPU and processor combination. However, it has a shorter battery life and is less portable than the Lenovo Legion Slim 5. The Lenovo, on the other hand, is more affordable and has a better screen aspect ratio, making it preferable for productivity and media consumption. It also provides a longer battery life, making it a good option for users who prioritize mobility and longevity on a single charge. Both have sufficient power for general use and are capable of demanding tasks like 3D modeling or machine learning, but the ASUS may edge out slightly in raw performance while the Lenovo offers better portability and value.

"Aside from all the chassis updates, the new TUF Gaming is most notable for its much higher TGP target of 140 W compared to only 95 W on the previous generation. PC makers everywhere are using the same GeForce GPUs this year since Nvidia has yet to launch the successor to the mobile RTX 3000 series. The more demanding processors of the new TUF Gaming has directly impacted battery life and the size of the AC adapter. Don't expect runtimes to be longer than on the previous generation under most conditions and be prepared to carry around an even larger AC adapter than before."

"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."
