I would advise against the ASUS Zenbook Pro. The Zenbook Pro uses a PenTile (RG/BW) not-true-4K display. The RGB in each pixel is replaced with either only RG or only BW. This means you get all the risk for content scaling issues with 4K, without the full sharpness of 4K to "make up for it". ASUS does this on all their current high-res offerings, and it's commonly regarded to be deceptive marketing. You might be interested in the info on this listed on the sidebar at https://www.reddit.com/r/SuggestALaptop/ If your eyes are good, 4K can be nice for software-dev and general productivity, in that you'll be able to turn scaling settings below 200% and get more screen realestate. However if you turn scaling settings below 200% on a not-true-4K display, things might start looking a little weird due to the incomplete matrix. If you're in it for the 4K, true 4K displays can be found in the Dell XPS 15, Lenovo Yoga 720, Lenovo Thinkpad P50, and others I described in this reddit post: https://www.reddit.com/r/videography/comments/657o1r/can_you_beat_this_juiced_up_laptop_asus_zenbook/dg86fn9/ If not, a Thinkpad P50 would probably be a great choice even if you're not going for the 4K display option on it. You can bring it to your desired RAM/SSD configs by doing the upgrades yourself.
