The ASUS ZenBook Pro Duo 15 generally costs more but offers superior performance for intensive engineering tasks, creative work, and gaming, thanks to its high-end processor and graphics card. The dual-screen feature, with a main OLED display, enhances multitasking and is touch-enabled for direct interaction. However, it's heavier and has lower portability. The Lenovo Legion Slim 5 is more affordable and still well-suited for general use, gaming, and some engineering tasks, but with a less powerful processor and graphics card compared to the ASUS. It offers good portability and higher refresh rate for smoother visuals in fast-paced games, but sacrifices screen resolution and the premium features found in the ASUS. Give Feedback

"Benchmarks aside, the Asus ZenBook Pro Duo is hard to compare with other PCs. Its closest competition may be a multi-monitor desktop, or a laptop with an attached travel monitor. The Pro Duo is more portable and versatile than either of those options, especially with the software tools Asus has thrown on top. For a certain niche of artists, media creators, and gamers, all that might add up to something special, even if it’s unattainable for the rest of us."

"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."
