Minergain has a real time comparison between Slush and Kano on the home page for the past week, month, quarter and year in CDT (Coins per Day per TH/s).  Multiply all of your miner's hash rate by those values and it will give you what you "would have" made if you were fully ramped up on each.  The week value is not extremely valuable since we have been working on the current block for almost 6 days now.  The quarter one is a little iffy because we had two 800%+ blocks in October.  The biggest one to consider is that 365 days times .00041726 times 13.5 gives 2.056 BTC for the last year for one S9 miner at Kano and 1.8971 BTC for Slush.  Obviously difficulty increases and variance will impact that number for 2018, but there is no contest which pool to be in over the long term.  Oh, and yes, Slush does pay tx fees, and these calculations include those super high ones that Slush was seeing so frequently.
