"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."

"The Gigabyte Aorus 15X is a strong showing of Raptor Lake and RTX 4000 series. While the Aorus had trouble keeping up in older games like Grand Theft Auto V, it nudged past the competition in Shadow of the Tomb Raider. It also flexed its next-generation muscle in Far Cry 6 and Borderlands 3. While we were impressed with the overall build quality and design of the Aorus 15X, the keyboard lacked good tactile feedback. The display performed well in real-world testing despite its on-paper shortcoming with brightness, but the speakers are lackluster at best."
