Florian Glaser | March 2023
"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."

Allen Ngo | April 2022
"The MSI Stealth GS77 is better than the GS76... mostly. The GS77 is a few steps forward and a few steps back from the GS76. Improvements are numerous including the stronger and more rigid skeleton, higher resolution webcam, larger clickpad, easier serviceability, relatively similar battery runtimes, newer display options, and higher performance at about the same TDP and TGP levels as before. CPU performance is better than expected even when compared to other laptops with Core i7 or Core i9 processors. The newer model feels more substantial than the outgoing one for higher quality impressions as well."
