I hope it answers your question
Nobody said that sumokoin gui easyminer is faster than xmr stak. Its just easier to use like its name says (Its faster than xmr stak in older cpus) However the difference is not that big, most likely you were not using all threads or didnt set cpu priority to high.
You are taking in consideration the results of both miners after just seconds of mining (3 or 4 shares just submitted from each sumokoin easy miner and xmr stak miner) you should leave them for some minutes for the hash rate to settle at an actual average price in order to compare safely. In any case mine with the miner that pleases you most. Sumokoin easy miner was built with ease of use in mind and this is its main purpose
