The Eluktronics Mech-15 G3R offers a higher resolution display which is great for visual clarity, but has a lower battery life compared to the MSI Stealth GS66. If you value a lighter device with longer battery life and improved portability, the MSI might be better for you, despite having a lower resolution screen. Both laptops have powerful processors and graphics, making them suitable for gaming, 3D rendering, and engineering tasks. Consider if the benefits of a higher screen resolution and improved color accuracy found in the Eluktronics outweigh the MSI's benefits of battery life and portability for your specific needs.

The Eluktronics Mech-15 G3R has a better screen than the MSI Stealth GS66 for general use, engineering and design, software development, and content creation.
The Eluktronics Mech-15 G3R likely offers superior image clarity and color representation due to its higher resolution and brightness, which enhances the experience for general use and engineering design tasks that rely on accurate color reproduction and detail. The MSI Stealth GS66, with a slightly lower emphasis on screen brightness and color gamut, still provides a good balance for general activities and design work, but may not be as vivid or clear. Both laptops, however, fall short for gaming and 3D work due to lower refresh rates which can lead to less smooth visuals in fast-paced environments.

Aaron Ritchie | September 2022
"Everything considered, the XMG Neo 15 (Mech-15 G3R) with RTX 3070 Ti is a great gaming performer. The combination of the Ti graphics card with the new Intel 12th gen CPU is enough to go toe-to-toe, and even slightly pull ahead of the RTX 3080 in most titles, though on games with Ray-Tracing enabled, particularly with graphics set to the maximum and on higher resolutions, the additional VRAM of the RTX 3080 makes a big impact, and the 8GB RTX 3070 Ti machine simply can’t compete, even with the more powerful processor."

"The MSI Stealth GS66 is powerful enough for QHD. The Core i7-12700H and the GeForce RTX 3070 Ti found in the 12UGS model that we tested run all modern games smoothly in the native QHD resolution. The 15-inch display is very fast with its 240 Hz refresh rate, and it also offers a great color space (almost 100% DCI-P3) on top of that, which should please gamers as well as content creators, although we would have still wished for a higher brightness. Case, input devices, and connectivity (Thunderbolt 4) are at a good level. However, among other things, the GS66 loses points due to the high temperature development in 3D mode and its poor webcam."
