Should G-Sync be the deciding factor on a laptop purchase?

I've done a lot of searching and drilled in on some of the important elements of this decision. I want this to be a desktop replacement as anything at or above an i5 8300H, 1060 and 60hz display would be better than my desktop anyway. I will be taking this with me to my University classes every day. However, size and weight seem to be one of the more subjective elements to this purchase and one that I can't really pinpoint what I want or what would be best for me. I've narrowed my selections to the Lenovo Y740 and Eluktronics Mech-15 or Mech-17. Lenovo's student discount or current memorial day sale brings the Y740 into price parity with both Eluktronics laptops. This brings us to the question I posed in the title. The Y740 has G-Sync whereas both the Eluktronics simply have 144hz displays. So, should g-sync be the deciding factor? If not for the Y740's G-sync display, I would have already purchased an Eluktronics laptop. Other factors I've considered: both Eluktronics have a smaller footprint then their Y740 counterparts. Y740-15 doesn't have a 10-key, the Mech-17 has Windows Hello support, the Y740-15 has poor webcam placement, both Eluktronics have mechanical keyboards, the Mech-17 has a non max-q 2070, and Eluktronics will have a more questionable resale value 2-3 years down the line.

GSYNC with MUX (switchable Optimus) is always the best solution imo. Y740 has MUX
