Looking at two gaming laptops

Looking At this one My local best buy has this open box for 900

https://www.amazon.com/Asus-GL702VM-DB71-17-3-Inch-i7-6700HQ-7200RPM/dp/B01KB0X0OQ/ref=sr_1_1?ie=UTF8&qid=1496510275&sr=8-1&keywords=asus%2Bg702&th=1

Then theres a guy near me selling this model on craigslist he bought it recently even texted me the receipt to prove it for 1000 Even with a case and an xbox one controller

https://www.amazon.com/MSI-GT62VR-Dominator-Pro-087-i7-6700HQ/dp/B01LWZI08T/ref=sr_1_1?ie=UTF8&qid=1496510472&sr=8-1&keywords=gt62vr+dominator+pro

Which laptop is the better deal the open box asus has no box and I can at least put geek squad warranty on it where as the craigslist one he has the original box I know its still under warranty because he showed me the receipt

I know the msi has a better video card but I feel the asus has a better build quality and I feel an overall nicer design and form factor as well as a 17 inch screen both are gsync

Any advice?
