Basically, BTC ASICs are 700x more efficient than GPUs. LTC (and other SCrypt ASICs) are expected to only be ~20x more efficient.
By making ASICs less efficient, it keeps more of the control of network in the hands of the individuals. SCrypt is the better hashing algorithm for ANY self-proclaimed libertarian, who wishes to remove power from the ASICs that have taken over the BTC network.

In comparison, your typical R9 290X is hitting 0.8 Litecoin MH/s in 300 Watts.
Your typical Litecoin ASIC Miner is ~26x more power efficient than a GPU.
The 290x hits ~850 MH/s with Bitcoin at 300 Watts. But ASICs will soon hit 600,000 MH/s at 300 Watts. http://www.butterflylabs.com/monarch/
