Litecoin is not special, it is just one of the many altcoins that we can choose from. Why in the world is Litecoin worth $10
LTC is better than other script alt coins the same way that BTC is better that other SHA256 coins - first, biggest market cap, widely accepted by merchants, exchanges, hard to break because of network hashrate....
LTC isn't just one of the many altcoins - many other altcoins are more or less (usually more) LTC clones.
