The Dell Alienware m15 R7 is a premium laptop with higher performance, suitable for intensive tasks such as gaming, 3D modeling, and machine learning, thanks to its powerful processor and dedicated graphics card. However, it is bulkier and has a shorter battery life, which detracts from its portability. On the other hand, the Dell Inspiron 14 7435 is more affordable, with sufficient capabilities for everyday tasks and general use, alongside better portability due to its lighter weight and longer battery life. It's also a 2-in-1 convertible, offering flexibility as both a laptop and a tablet. Your choice should hinge on whether high performance or portability and cost savings are your primary concern.

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."

"We see no shame in an economy laptop missing the four-star mark. Frankly, we considered giving the Inspiron 14 2-in-1 three-and-a-half stars for its low price, competitive performance, and long battery life. Unfortunately, working with a screen that can't deliver at least 300 nits of brightness is simply no fun to the point of detrimental. Still, if you're looking for a convertible laptop on a tight budget, it's worth keeping an eye on Dell's sales and discounts. That Lavender Blue model is fairly tempting."
