"The Asus ROG Zephyrus G14 offers an impressive package. Asus improves the performance of the new 2023 ROG Zephyrus G14 considerable and offers a very powerful 14-inch notebook with plenty of performance for gamers and content creators. The high-quality chassis is unchanged from last year, but is now equipped with the latest and greatest from AMD as well as Nvidia. The Mini-LED panel also puts up a convincing performance in pretty much every regard, even though the MacBook Pro 14 still offers superior brightness values. The panel works extremely well for gaming and the included color profiles offer very accurate colors."
"Dell's Inspiron 15 (3525) is a peppy-enough and affordable-enough home or remote work machine, but it's not very ambitious; it does little to go beyond the basics. More the concern: It’s readily overshadowed by a number of machines that outperform and outclass it. Even if the Inspiron can get the job done today, its competition has the mettle to keep doing the job tomorrow in a way the Inspiron simply can’t promise. Plus, those alternatives are much more enjoyable after work."
