Do you have a link? MtRed would become one of the most popular pools if that were true.
Nobody can compete with 0% PPS.
btcguild is PPS and has not a fixed fee, so it should be the best one for casual and not so casual miners, did you look into it?
spiccioli.
I've mined at BTCguild for ages, it's just another proportional pool which has all the problems of pool hopping. The 0% fee is irrelevant because of the flawed distribution model of rewards.
PPS means you get paid for every single share you submit (fixed amount). Other pools have modified PPS schemes that are not the same thing (SMPPS, PPLNS)
No pool hopping penalties, 24/7 miner rewards, or incentive to jump in during the beginning of rounds, just getting paid for what you contribute. Pure PPS is effectively 0 variance over any time period.
The problem being that you need quite a lot of BTC in buffer to pull it off, in case of bad luck streaks and very long rounds.
Deepbit is the only pool which offers pure PPS rewards, at a hefty fee (10%)
