If you prioritize top-notch performance for intensive tasks like 3D modeling, machine learning, or gaming, and don't mind less portability and a higher price, the Dell Alienware m15 R7, with its more powerful processor and graphics card, is suitable. Alternatively, for general use or less demanding gaming, the HP Omen 15, being lighter and less costly with ample performance for everyday tasks, offers a balanced option. Additionally, consider battery life; Alienware tends to consume more power due to its higher performance hardware, which could mean more frequent charging compared to the Omen. Give Feedback

Tom's Hardware
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."

Florian Glaser | January 2021
"We consider around 1,260 Euros (~$1530) for a Ryzen 7 4800H, a GeForce RTX 2060, a 512 GB SSD and 16 GB dual-channel RAM to be a good offer that appeals to price-conscious gamers. Very high details are rarely a problem in the native resolution of 1,920 x 1,080. Buyers will also be spoiled with a top-notch battery life that even beats most other notebook classes. If HP now improves the speed of the WLAN module, the stability of the case and the repeatedly criticized picture quality, the competition will have to dress extra warmly."
