Jared Newman | August 2021
"Benchmarks aside, the Asus ZenBook Pro Duo is hard to compare with other PCs. Its closest competition may be a multi-monitor desktop, or a laptop with an attached travel monitor. The Pro Duo is more portable and versatile than either of those options, especially with the software tools Asus has thrown on top. For a certain niche of artists, media creators, and gamers, all that might add up to something special, even if it’s unattainable for the rest of us."

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."
