For a balance of performance and portability with a high-quality screen suitable for engineering tasks and intensive gaming, the ASUS ROG Zephyrus G15 is a strong choice, despite its higher price point. It offers a more powerful GPU and CPU, a higher resolution and refresh rate display, and superior color accuracy, which is crucial for detailed work and immersive gaming. However, if budget is a concern and you prioritize longer battery life with decent performance for general use and light gaming, the Lenovo LOQ 15i is a viable option, though it falls short in terms of screen quality and overall performance compared to the ASUS.

How the ASUS ROG Zephyrus G15 and the Lenovo LOQ 15i compare to other laptops
"As long as you're aware of the fact that the GeForce RTX 3080 laptop version can only unfold its potential to a limited extent due to Asus's low TDP setting and that it can be slower than a fast RTX 3070 laptop, the ROG Zephyrus G15 GA503Q cuts a fine figure. One of the biggest highlights turns out to be the WQHD panel, since it attracts customers with 165 Hz, relatively fast response times, FreeSync, and good color-space coverage. Other selling points are the surprisingly rich sound, the long battery life, and the sleek design. In terms of looks, the white edition stands out nicely from the competition."
"Even after a short time with the LOQ 15, you'll find it has a lot going for it, but ultimately it's just "good"—not quite a star. The performance is respectable for the hardware it’s running, but Lenovo had to make some design sacrifices to trim the price. One of the better aspects is the keyboard, making it one of the better low-cost gaming laptops to actually put your hands on."
