An all-black metallic plus plastic combination earns the soul of M15. We get to see two different metals composing two distinct styles. The plastic chassis gives a hard time to its aluminum hinge. The deep black theme puts forth the minimal and the elegant aesthetics within the design.

This model is pretty much light-weighted which abides by the rules of lightness carried by the laptop. The weight over here is 1.9kg which is minimal making the laptop handy. The most significance feature over here is the presence of thunderbolt 3 which is the absolute favorite of gamers alongside the presence of Ethernet and double type-c USB ports, combining with the 3.5mm headphone jack.

All these connectivity ports are also a part of the design within GS66 Stealth. This laptop is also significant because of its recent upgrade in terms of the deep black theme. The theme combines with the aluminum build making it a decent model.


So, the story is that we get to find similarities when it comes to the display of the models. Both of the display screen sizes are of 15.6 inches which is an ideal size followed by the mighty IPS technology. This technology comes with the finest resolution quality of 1920×1080 pixels which bears the respective HD nature. What fascinates the users most is the presence of similar refresh rates within both of the devices making the value up to 240Hz which means an impressive display with finest display settings.

The battle amidst speakers declares M15 as the ultimate ruler. Though, both of them possess dual speakers but the nature differs in each one. M15’s speakers are known for their advanced bass settings and perfect sound effect. On the contrary, GS66 Stealth lacks this level of bass adjustment and amplification settings. So, the sound isn’t that much crystal-clear over here.


We know that both of the laptops are a representation of modern technology in their overall design and functioning. So, one can expect the most important input device extremely significant over here. The keyboards located within both are backlit which means that you are going to get the 4-Zone RGB technology as an additional benefit. M15’s keys are thicker in size compared to the mediocre keyboard present in GS66 Stealth. This gives the former an upper hand over the other one.

The touchpad is entirely made up of precise drivers in both. Though, the touchpad’s area in GS66 Stealth is a bit narrower yet the sensitivity towards touch is admirable. Sadly, there is no fingerprint mechanism located in both. But, other than that the touchpad is really nice and sensitive enough to respond in both.


M15 does not come with any camera at all. This is a bit surprising for the users since every single laptop these days comes with a camera. The main reason behind the absence is the claim that this laptop is purely built for gamers to maximize the gaming experience. GS66 Stealth, comes with a 720 pixels camera which serves finally in managing long video recording gaming sessions.

Both of them possess a 4-celled battery. The difference lies in between the battery capacity of both the devices. We get to see a 90Wh battery capacity in MSI GS66 Stealth which gives it enough strength to last up to a period of 7 hours on a total count. M15’s 80Wh battery capacity holds everything finely till 6 hours approximately.


GS66 Stealth is a bit more expensive than the other. The chief reason behind the unexpected heightened price is the presence of a premium quality design which contributes a lot in its overall functioning. Though the laptop is available in three different display rate variants, still the least one initiates at $1,400. On the flip side of the coin, M15 initiates at a price of $1,200.


ASUS ROG Zephyrus M15 serves you best when it comes to the pro level performance. The fantastic display is obviously a big factor for the praise of this beast. The display combines with the audio system as well as the fast processor to give you a best gaming experience cooperating well with the design. Although, MSI GS66 Stealth’s design is to die for. Still, the design on the whole does not seem as impressive when looked from the perspective of functioning and premium price.
