Although they have very similar scores, PerfectRec considers Dell XPS 15 to be very good for general use, while the Lenovo Legion 7 is good.
The Dell XPS 15 offers a good balance for general use with its high screen brightness and slightly lighter weight, making it more portable and better for various lighting conditions while still providing solid performance and battery life. The Lenovo Legion 7, a bulkier option with a higher-resolution screen and substantial graphics capabilities, excels in tasks demanding more power like gaming, but its heavier weight and reduced battery life make it less ideal for frequent mobility.

"The 2023 Dell XPS 15 is more or less exactly what you'd expect from the company flagship. Its fresh components deliver measurably superior power and longevity, while the machine's premium build and design remain intact. It may not be overly exciting, but XPS loyalists and upgraders should be more than happy."

"The Lenovo Legion 7 is a fast 16-inch gamer with 165 Hz display. The new Lenovo Legion 7 is a very good gaming notebook that, despite its comparatively compact compact 16-inch case, does not have to do without the most powerful components. Thanks to good cooling, no compromises are made in terms of performance. Both the Core i9-12900HX and the GeForce RTX 3080 Ti perform at a very high level."
