I have switched to Kano today as well after reading this thread. I was on Slushpool for about 5 days. I'm new to mining, so learning and trying things out.
Was getting around 0.00003000 BTC per block on Slushpool, they could come up between 4 and 8 times a day. 
So on Slushpool since 13th Sept till end of Sept 17th, a 1.1Th/s (Antminer s5) made 0.00192176BTC.  So around 0.00048044BTC a day on average.

So I'll leave it on Kano for a week and see if there is a noticeable difference.
