For a balance of performance and versatility, the ASUS ROG Flow Z13 is a strong contender. It offers a high-performance Intel i9 processor and a capable Nvidia RTX 4050 GPU, making it suitable for demanding tasks like gaming, 3D rendering, and machine learning. The vibrant 2560 x 1600 touchscreen display with a 165Hz refresh rate is excellent for fast-motion content and has superior color accuracy, which is great for creative work. It's also detachable, providing tablet functionality. However, it's pricier and has a shorter battery life compared to the Lenovo LOQ 15i.
On the other hand, the Lenovo LOQ 15i is a more budget-friendly option with a lower price point and longer battery life. It still delivers solid performance with an Intel i7 processor and an Nvidia RTX 4060 GPU, which is slightly more powerful than the ASUS's GPU for certain tasks. The 15.6-inch screen with a 144Hz refresh rate is decent for general use and gaming, though it lacks a touchscreen and has lower color accuracy. It's also more traditional in design, focusing on laptop use without the tablet feature.
In summary, if you value a high-quality display, tablet functionality, and top-tier performance, and are willing to pay more and charge more frequently, the ASUS ROG Flow Z13 is the way to go. If you're looking for a more cost-effective solution with longer battery life and are okay with a slightly less vibrant screen without touch capabilities, the Lenovo LOQ 15i would be a better fit.

How the ASUS ROG Flow Z13 and the Lenovo LOQ 15i compare to other laptops
"The Asus ROG Flow Z13 is a gaming tablet with powerful Alder Lake i9 CPU. The ROG Flow Z13 impresses with its good cooling. After our review, the impression is predominantly positive. Besides a very fast Alder Lake CPU and stable gaming performance, especially the cooling system is surprisingly effective and quiet. You can use the integrated speakers without any issues while gaming. The 1200p display in the 16:10 format also impresses with good color reproduction and high brightness. Since the battery runtimes aren't particularly long as it is, we wouldn't recommend the optional 4K panel."
"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."
