External Monitors for My Alienware

So I'm looking to get two monitors to do a dual screen setup to hookup to my Alienware 15 R2 laptop. Need a dual setup for when I'm working on my college stuff, when working from home. I like it for my casual computer use as well, makes things easier.

Here's the two models that I started looking at;

Alienware 25 Gaming Monitor: AW2518H:

Dell 24 Gaming Monitor: S2417DG:

Which is overall better?
