If you need a laptop for heavy gaming, 3D modeling, or intensive tasks and don't mind spending more, the Asus ROG Strix G18 is a powerful choice, though less portable and with a shorter battery life. However, if you prefer something more affordable, lightweight, and with a longer battery life for everyday use, web browsing, and light productivity, the Lenovo Flex 5 14 offers versatility and value but won't handle demanding software as well.

The ASUS ROG Strix G18 (2024) is very good for general use, while the Lenovo Flex 5 14 is good.
The ASUS ROG Strix G18 offers high-end CPU and RAM, ensuring fast performance for demanding tasks and multitasking, along with superior screen quality for crisp visuals, but it's less portable and has shorter battery life compared to many rivals. In contrast, the Lenovo Flex 5 14 provides good performance for everyday use with decent portability and battery life, making it a solid choice for those who prioritize mobility and longer use on a single charge, though it may not handle intensive tasks as smoothly as the ASUS.

The ASUS ROG Strix G18 (2024) is very good for gaming and AI, while the Lenovo Flex 5 14 is only fair.
The ASUS ROG Strix G18, with its superior GPU and high screen refresh rate, offers an immersive and smooth experience for gaming and 3D tasks, which justifies a higher price and potentially less portability. Conversely, the Lenovo Flex 5 14, while offering decent performance and screen quality for casual use and flexibility as a 2-in-1 device, may not meet the demands of intensive gaming or 3D applications due to its more modest GPU and lower screen refresh rate.

The ASUS ROG Strix G18 (2024) is excellent for engineering and design, while the Lenovo Flex 5 14 is good.
The ASUS ROG Strix G18 is equipped with a more powerful CPU, more RAM, and a superior GPU, which translates into faster and smoother performance for demanding tasks like 3D rendering and simulations, complemented by a high-quality screen for precise visual work. The Lenovo Flex 5 14, while still capable of handling engineering software, offers greater portability and a flexible form factor at the expense of some performance, making it more suitable for general use and less resource-intensive engineering tasks.

The ASUS ROG Strix G18 has a better screen than the Lenovo Flex 5 14 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Strix G18 boasts a high-resolution display and excellent color accuracy, which makes it ideal for engineering and design tasks that require precise color representation, but its lower refresh rate may not be optimal for gaming or 3D work, where smoother motion is key. On the other hand, the Lenovo Flex 5 14 offers an adequate display for everyday tasks and casual design work, but its limited color range and lower brightness may not satisfy professionals who need more vivid and accurate colors. Additionally, both laptops' screens might not provide the best experience for gaming or 3D applications due to their poor refresh rates, which can result in less fluid visuals during fast action scenes or animations.

"With the ROG Strix G18, Asus has made an almost consistently good debut in the still quite new 18-inch laptop segment. The base unit case shows a few signs of weakness in the area of stability and is something which has an effect on the perceived quality of the input devices (the chassis tends to rattle a bit). Nevertheless, thanks to generous port features (incl. Thunderbolt 4), a striking design, and extensive lighting (keyboard, LED strip on the front), gamers get a fitting gaming platform."
"The highlight of the latest IdeaPad Flex 5 14 is clearly its AMD CPU. The octa-core Ryzen 7 5700U is insanely fast even when compared to the best Tiger Lake Ultrabooks in the market or even Core H CPUs in many gaming laptops. It's a lot of raw processing power for what is supposed to be a budget 14-inch convertible. If your daily workloads can benefit from extra multi-thread CPU performance, then look no further than the inexpensive AMD-powered Lenovo IdeaPad Flex 5 14. For regular on-the-road browsing or video streaming, however, a slimmer and lighter 10th gen Core Yoga, Spectre, or XPS would be a more balanced option."
