Considering you're looking at the ASUS ROG Flow X13 and the Lenovo LOQ 15, you'll face several key tradeoffs. The ASUS boasts a more powerful GPU and a higher-resolution touchscreen display, which makes it a better choice for demanding graphics tasks like gaming, 3D rendering, or machine learning. It's also more portable due to its lighter weight and smaller screen size, but it comes at a premium price. On the other hand, the Lenovo is less expensive, yet offers a larger screen size, though with a lower resolution and without touch capability, making it suitable for general use and less intensive engineering tasks. The Lenovo's battery life is also shorter, and the laptop is heavier, which may impact its portability. Give Feedback

The ASUS ROG Flow X13 has a better screen than the Lenovo LOQ 15 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Flow X13 stands out for general use with its high-resolution display that delivers sharp text and images, and its brightness makes it easy to view in various lighting conditions. For engineering and design, this laptop's display offers a wide color gamut, which ensures accurate color representation crucial for detailed work. However, its lower refresh rate hampers the gaming and 3D experience, where smooth motion is key, and thus may not be ideal for those specific activities. The Lenovo LOQ 15, while having good resolution and brightness for everyday tasks, similarly has a good color gamut for professional design work, yet also falls short for gaming and 3D due to a less optimal refresh rate.

Sebastian Bade | February 2021
"The Asus ROG Flow X13 is not an off-the-shelf convertible. This quickly becomes clear when you take a closer look at the technical specs. The AMD Ryzen 9 5980HS is a state-of-the-art SoC with 8 cores and 16 threads, which also makes the 2-in-1 interesting as a work device. With 32 GB of RAM and a 1 TB SSD, gamers are also well taken care of. The dedicated Nvidia GeForce GTX 1650 Max-Q fits well into the overall concept and ensures a solid 3D performance. With the eGPU dock, which is equipped with a GeForce RTX 3080, the small convertible transforms into a full-fledged desktop replacement in terms of performance."

"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."
