Alienware makes the best gaming laptops, as in their looks, their design, and there software. I would say 100 dollars for their name, 100 dollars for design, and that’s pretty much it. I guess the Asus is a better, more reliable laptop, while still being cheaper.
Don't even look at the asus g51jx-xi I believe that might be the one that was discontinued due to bsod. I believe they are coming out with another to replace it which I think is ag51jh-a1,however alienware makes a great laptop ,definitly overpriced but compared to falcon northwest laptop not so bad.
Apple? For some like me yes, for my dad and sister, no.
Alienware? Depends on if you like their design and prefer their support (which I have found to be better than typical DELL).
I like many of the Alienware designs, and I have recommended some of their desktop build for friends who want a little above the norm and want a brand name and not DIY.
For a laptop, I prefer a few other makers because of the options I look for, but if Alienware made a sweeter 17" I might consider it cause their M17 doesn't offer an MHD5 series yet. They also cripple their Studio 17s now too to make the ALienware look better.
Although I'd still prefer a return to VooDoo's roots between the two as they did a better job of putting together top features, and they used to have fantastic support prior to HP.
Currently though I prefer Eurocom for 17", although by the time I buy there'll likely be more options.
Essentially Alienware is a niche/boutique brand, it's not about band for your buck but niceties that some people might prefer over value.
