I know that in general, both the laptops have almost same specs. This is not for myself, asking for a friend. He wants a sleek laptop with good gaming capabilities that makes a style statement too. I recommended him the XPS 15 9550 i7 variant. Did I do right by him? He did some research himself and likes the Dell but can't decide between the Lenovo Y700 and the Dell. The Lenovo is cheaper and provides slightly better battery life whereas the Dell is downright gorgeous and future-proof but expensive.
Basically: better Battery life+ Cheaper vs Better aesthetics+ thunderbolt and hence future-proof(eg usable with Razer Core)
