Lets compare it with the M17x shall we? since both are overpriced gamign laptops anyways:
Core: While Blade has a faster core, M17x has more processing power
Blade: I7 dual-core at 2.8 Ghz
M17x Econ: I7 Quad-core at 2.0 Ghz
M17x Max: I7 Quad-core at 2.3 Ghz
Memory: Depends on the version of Alienware you get.
Blade: 8 gig DDR3
M17x Econ: 4 Gig dual-channel DDR3
M17x Max: 16 gig dual-channel DDR3
Video Card: Went over it, Raqzer beats the econ, but fails against even the next runner up, let alone max
Display: Too similar to argue a difference
Hard Drive Space: Well, even the economy version has a terabyte of space, so about three times blade's.
Battery:
Alienware: High Capacity 9-cell Lithium Ion (90-WHr) (more likely to explode and spew fiery death)
Blade: Integrated 60Wh battery
Weight/thickness:
M17x: about 10 pounds, bulky
Blade: about 7 pounds, thinner
Price:
M17x Econ: About 1.5k
Blade: about 3k
M17x Max: about 3k
Well, this is going off of my limited knowledge of computers, but I'd say that the Blade barely surpasses the M17x Economy value, and has a much lower chance of finding a coupon to buy it with too. More or less the Economy one is half the price, but slightly less "high-tech" and lacks the little side-panel.
That being said, if you are getting a computer that is going to trump all computers, you aren't likely woried about pricing, and to be frank, the M17x with its better Specs has a slightly slower core, but twice the processing power and three times the memory, even if it's not at max, for about the same price... The only big difference is the blade's side panel.
Thus, I say, that Alienware wins and Razer can suck it.
