If cost is a primary concern and your tasks are basic such as browsing, office work, and media consumption, the Acer Aspire 5 15 is a budget-friendly choice that will meet these needs. However, if you require a laptop for resource-intensive activities like gaming, 3D modeling, or high-end graphic design, the Lenovo Legion 9i, while more expensive, offers superior performance and is better equipped to handle these demands. Keep in mind that the Legion 9i may also have a shorter battery life due to its powerful components and may be heavier, reducing its portability compared to the lighter Acer Aspire 5 15.

The Lenovo Legion 9i has a better screen than the Acer Aspire 5 15 for general use, gaming and AI, engineering and design, content creation, and software development.
The Acer Aspire 5 15 offers adequate resolution and brightness for everyday tasks, but its panel type may not display colors as vibrantly, reducing its suitability for precise engineering work and providing a less immersive gaming experience. The Lenovo Legion 9i shines with high-resolution and bright display, enhancing visual clarity for all users and providing wide color gamuts crucial for accurate color representation in engineering and design. However, its lower refresh rate, while not impacting general or engineering use significantly, can diminish the gaming experience where higher refresh rates are key for smooth motion rendering.

Sascha Mölck | November 2022
"The Acer Aspire 5 15 is a good value office laptop with reasonable battery life. The combination of slim exterior, relatively low weight (approx. 1.7 kg) and 8 hour real-life battery runtime makes the Acer Aspire a truly mobile laptop. The modest Tiger Lake processor supports this area and simultaneously ensures an affordable price point. The Aspire produces little noise and stays cool. The screen (FHD, IPS) might not win any prizes but is entirely appropriate for the price."

Matthew Buzzi | December 2023
"The Lenovo Legion 9i is meant as a top-end flagship showcase for enthusiasts, and on that, it delivers. You'll find flashier designs in this price tier—Razer’s all-metal build in a similarly sized laptop like the Blade 16, or monstrous 18-inch machines—but this is a well-thought-out laptop. The chassis is trim for a 16-inch powerhouse, the lid is unique, and bespoke liquid cooling takes performance to the next level."
