nope, because all those other crapcoins hold the 'value' of LTC down. except for other settings these coins are just copycats. maybe except YAC.
And why would YAC be special?
as long as its not possible to mine with gpu it is something different because not everyone has a botnet or is hosting amazon servers.
so it is different to ltc in a simple way but at least it is something. take all other scrypt coins. they are allways the same except for block rewards und time between blocks.
