Sure i dug it up for you. This show the difference based on actual payouts over X time. You'll see how significant antpool's fee. And on tap of that if you mine for antpool you support centralization of the hashrate.

Your concern about centralization is a true and serious one, and a threath that everybody must be aware of.
I have analysed the results.If the pool is big, their performance is more stable.On the otherhand if the pool is small it can perform better or worse compared to others, on the long term their income will be nearly the same.
You are right about extra payments.I change my second pool to Kano.
Very nice
Yes Kano takes 0.9% so its lower than "0%" minus 100% tx fee. Also Kano's pool is highly optimised code with a very low orphan count. So if we could get the hashrate there back up, we could have more "stable" return. But regardless, its been doing very awesome since i joined. After the 666.666666% block anyways
