The ASUS Vivobook 15X is a lower midrange laptop that has a larger battery and marginally better multi-use performance capabilities, which might make it suitable for more intensive tasks such as light engineering and 3D work. However, its portability is reduced and it's notably more expensive than the Lenovo IdeaPad Slim 3. On the other hand, the IdeaPad Slim 3 is positioned as a budget laptop with good battery life and a touchscreen display, making it more affordable and offering more hours of typical usage between charges. It's slightly more portable and has a better build quality. If you prioritize a touch screen and higher portability on a tighter budget, the Lenovo Ideapad Slim 3 would suit you, but if you need slightly better performance for demanding applications with a higher price tag, the ASUS Vivobook 15X might be the better choice.

The Lenovo IdeaPad Slim 3 has a better screen than the ASUS Vivobook 15X for general use, engineering and design, and content creation.
For general use, both the ASUS Vivobook 15X and the Lenovo IdeaPad Slim 3 have displays that provide adequate resolution and brightness, but they don't use panels that stand out in terms of color or contrast, hence the 'fair' quality rating. Engineering and design tasks demand accurate color reproduction, and while these laptops offer decent coverage of color spaces, they don't fully meet the high standards required for professional color work that utilizes extensive DCI-P3 and Adobe RGB. For 3D applications, which heavily rely on smooth motion, the lower refresh rates on these laptops are a limiting factor and resolution and panel quality alone can't compensate for the lack of fluidity that higher refresh rates would provide.
Battery

The ASUS Vivobook 15X has 8 hours of battery life. The Lenovo IdeaPad Slim 3 has 10 hours of battery life.
Battery life estimate is based on a mix of common use patterns. More portable and higher performing laptops tend to have less battery life.

PORTABILITY SCORE

The ASUS Vivobook 15X and Lenovo IdeaPad Slim 3 are both good for general use.
The ASUS Vivobook 15X and the Lenovo IdeaPad Slim 3 are fair for general use because they both have capable processors and sufficient RAM for everyday tasks, with the ASUS having a slightly stronger CPU. While both feature a similar screen size and type with good quality displays, the Lenovo edges ahead with a better battery life and is slightly lighter, making it more portable; however, ASUS offers a backlit keyboard and a number pad which may be preferable for some users.

The ASUS Vivobook 15X and Lenovo IdeaPad Slim 3 are both only fair for engineering and design.
The ASUS Vivobook 15X and Lenovo IdeaPad Slim 3 are both considered fair for engineering and design use primarily due to the moderate power of their CPUs and graphic capabilities, which can handle mainstream tasks but may struggle with high-end engineering software and complex designs. While both models offer similar RAM and IPS screens with adequate resolution for clarity, the ASUS has a slightly better GPU for graphics-related tasks and the Lenovo provides touch input for more interactive design work; factors like speaker quality and operation noise are less critical but should still be considered given Lenovo's quieter operation and ASUS's satisfactory audio output.

"All in all, my day on the Vivobook had its ups and downs. It is a really pretty and well-built device, and it had all of the functionality I needed to get me through my browser-based workload. But the speakers weren’t my favorite, and the battery life was just too short."

"The Lenovo IdeaPad 3i is decent for use as a workstation. Its Intel CPU and integrated graphics can only handle light productivity tasks, not demanding workloads like video editing or 3D graphics. You also can't do any color-critical work because the available displays have a narrow color gamut. It has a good port selection, but its USB-C lacks Thunderbolt 4 support. On the upside, it has a comfortable keyboard and doesn't get hot or loud under load."
