I'd get the MSI for several reasons:
It sports legacy ports without further expense. I need RJ45 and USB.
More CPU power. Maybe it's not needed right now, but it will come very handy in a few years when Windows upgrades and updates make anything slower. Same goes for the more powerful GPU
MSI has got good reputation in the gaming community (or it used to) for being fast and reliable machines that can cope with overclocking even being laptops. An acquaintance of mine got a MSI like 4 years ago for gaming (not hardcore gamer) and he's still happy with it, zero problems.
