Brandon Hill | October 2022
"The Alienware M15 offers solid gaming and leading endurance. It makes the most of its CPU and GPU while delivering stellar battery life for a gaming laptop. Opening the lid presents a full-size keyboard with honeycomb cutouts above it on the deck. An oblong RBG lightning element surrounds the entire rear panel and can be color-synced with the other lights on the laptop. There’s not a lot to dislike about the M15 Its productivity performance lagged in some areas, particularly in the storage benchmark, and it’s a bit heavy. Alienware has a clear winner here with the M15 based on its strong overall performance and endurance."

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."
