For a balance of performance and portability, the ASUS ROG Flow X13 is a strong contender. It offers a high-resolution touchscreen display with excellent color accuracy, making it suitable for creative work and general use. Its compact size and lightweight design enhance its portability, while the powerful AMD Ryzen 9 processor and Nvidia RTX 4070 GPU cater to demanding tasks such as gaming and machine learning. However, this performance comes at a premium price and with a smaller screen than the Lenovo. On the other hand, the Lenovo LOQ 15i is a more budget-friendly option with a larger 15.6-inch display, which might be preferable for those who prioritize screen size and don't need the versatility of a 2-in-1 design. It still provides solid performance with an Intel i7 processor and Nvidia RTX 4060 GPU, suitable for general use and some gaming, though it may not match the ASUS in intensive tasks. The Lenovo also lacks a touchscreen and has a lower battery life, but it includes an Ethernet port and more USB-C ports, which could be beneficial for connectivity. In summary, if you value a high-quality display, portability, and top-tier performance for tasks like gaming and creative work, and you're willing to pay more for it, the ASUS ROG Flow X13 is the way to go. However, if you're looking for a more affordable laptop with a larger screen for general use and are okay with less battery life and no touchscreen, the Lenovo LOQ 15i would be a suitable choice.

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."
