Neither are the most portable options available, but between the two, the Lenovo is significantly lighter and easier to carry around.

Matthew Buzzi | July 2023
"Dell's Alienware m18 delivers on its promises: This is a large, powerful gaming laptop with the premium flair and feel you expect from an expensive purchase. The drawbacks are really the price and battery life, which in context are reasonable. (We'd also like to see more ports on the laptop's sides.) This price tier exists for deep-pocketed enthusiasts, and if you’re considering anything in this range, the m18 isn’t an outlier. For the majority of shoppers, of course, all of these mighty 18-inch systems are likely too expensive."

"The Lenovo Slim Pro 7 is an attractive, portable laptop that’s ideal if you need a combination of CPU and GPU performance. It also nails the fundamentals with solid connectivity, an enjoyable keyboard, a large touchpad, and top-notch webcam. Display quality is a weakness, but it’s an acceptable compromise for the laptop’s extremely competitive $1,199 MSRP. The Slim Pro 7 is a versatile, affordable laptop and hard to beat for the price."
