I have used slush for quite some time now. Payout is always on the next hour after you reach your payout thresh hold. Love the dashboard. Been somewhat modeling the one I have been working on after it. It is defiantly has the most user friendly stats all on the main page and is good and easy to understand for beginners.
This is what finally had me decide on slush: the dashboard they use. Easy for us beginners to understand, with very useful help/tutorial pages.
As I'm coming to understand things more, I am considering kano.is however. It seems luck isn't equal, and is dependent on h/w, s/w and internet connection amongst other things. Yes, only a few % points difference, but when you're talking about micro
BTC payouts, those few % points can matter.
