I just don't like PPS, pool owner takes away the "risk" of bad (and good!) luck at the cost of a huge fee: I prefer keeping the luck for a much lower fee.
There are 0% PPS pools like abcpool.co which means you have zero risk as well as zero fees.
If you don't mine in such a pool then you either support other models for ideological reasons, or like to earn less money for some masochistic reason.
With PPS, fee or no fee, you mine at a flat rate. So if, so called, luck is good you loose if it is bad then you win or least break even.
What do you call "ideological reasons"?
You get what you pay for. There is no such thing as a free ride.
