I like that Dell display (I mostly use Dell and LG displays) and most people should certainly save the money. The areas where the specs aren't the same are really significant though (e.g., resolution, as you noted, is a major difference despite only being one of the specs. Brightness, dynamic brightness, and size are also quite significant and drivers of major cost differences in just about any monitor comparison.)

Here's a spec overview for those unfamiliar. https://www.displayspecifications.com/en/comparison/4f37c07a...
