PPS vs PPLNS - 1900kb/s Stable

[simonc]

Hey guys

My Current Hashrate, is around 1700-1900kh/s for LTC, with about 2 Gpu's and 12 other cpus/machines
was wondering what's more rewarding, would that be PPS system (litecoinpool.org) or any other PPLNS site
i'm hashing 24/7

tried the PPLNS system but for some reason, makes me feel i get much less using this sytem
