In practice
Flypool represents + 40% of the strength of the network so on the block number possible they will necessarily find more regularly blocks (around 8 blocks per hour on the 24 block.) And remunere your sharing number on block find, Therefore mining the right block
And dwarfpool represents + 4% of the strength of the network so on the possible block number they will not necessarily find unblock per hour (around 0.8 block per hour on the 24 block.) And remunere on the global shares so no matter if You mined the right block or not
Dwarfpool is more risky because smaller so not on to find a block in the hour but if by chance it finds 1 + 1 more it is all benefit (has to see if you prefer stability or luck)
I prefer dwarfpool which because no matter what you have miner good or bad block you will pay on your level of sharing and not as on flypool on the chance to have done as much sharing as possible on the good block
To network equivalent dwarfpool is more linear
i have 1 rig (2 rx 470 4g + 2 rx 470 8g) 857h/s et 1 rig (4 rx 480 8g) 962h/s
on dwarfpool my ration is 0.24zec /day
