XPS 15 FHD vs Dell 7577 UHD

[Simazo]

Hi, please help me to decide one or another I should choose. I would use it mainly for video editing. One is with 4k screen and another with full HD. But I heard XPS has amazing screen it is accurate and sharp but 7577 would give me some work space. But is it not an overkill with 15'' 4k ? 7577 is a little bit bulky but what I need is just quality. Thanks
