In my case I pull in about 0.03btc each day on NH. So right now, that is what I'd be out if they don't pay me for yesterday. I switched all my rigs over the mph until NH pays me for yesterday.
I have done comparisons in the past between NH and MPH, and with NH now offering 0% fees to Coinbase, they edge out MPH in my most recent testing. Of course it all depends on the market, what coin to auto exchange to on MPH, etc. I did apples to apples, auto exchanging to BTC. NH is nice if you want a steady cash flow (NH >0%> Coinbase >1.5%> Checking Account) without speculating on which coins to hold, etc.
