Which Laptop would be better?

Hardware wise, there is no question the HP is better, the processor is an i5 and the graphics card is far better. Aesthetically it would be the alienware. There is no point getting an alienware if you aren't looking to max out our system, you'll be paying 500 for a laptop that looks cool and really cant do much. If your budget was larger i would suggest the alienware with better internal parts, but based on what you listed the hp is much much better
