The Dell Alienware m18 R1 offers powerful performance suitable for intensive gaming, 3D rendering, and high-processing tasks, reflected in its superior display, larger storage and memory, and stronger GPU, but it is less portable and has a lower battery life. In contrast, the Dell Inspiron 14 5420 is more affordable, portable, and has longer battery life, but is less suited for demanding activities due to its midrange processor, less memory, and a less powerful graphics card. If you need a high-performance device for computation-intensive work or gaming and don't mind the weight, go for the Alienware, whereas if you prioritize battery life and portability for general use, the Inspiron is a better choice.

The Dell Alienware m18 R1 is very good for general use, while the Dell Inspiron 14 5420 is good.
The Dell Alienware m18 R1 stands out for general use due to its high-performance CPU, ample RAM, large high-quality screen, and strong graphics capabilities, but these features come at the cost of portability and battery life.

"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."
"If laptops were food, then the Dell Inspiron 14 5420 is arguably a Big Mac. There are cheaper and more expensive options, but this arguably represents the baseline of quality and value in the world of mobile computing… something that’s underlined by the attractive $1,279 price tag."
