I always keep coming back to Slush (a noob story).
A few months ago I bought an S1. Brand new to the mining world and didn't know much about it (arguably, still don't). Based on a little research I chose Slush's as my first pool. I wanted to try a few different pools since I was so new and didn't really know how any of them would reward me for my one little S1.
Well, after trying five different pools, Slush's always wins and I alway come back. I think now I'm here to stay.
Admittedly, my experiment is non-scientific, not long enough to get a true sample and I bailed early on some pools, but from my experience, I earn the most with Slush.
With Slush, the time to payout .01 BTC was all over the place --- from 23 hrs to 84 hrs. With the rest it was never lower than 53 hrs --- usually more like 60 hrs and up.
Here's a little chart with the average-per-day earnings as I jumped around to different pools while testing my miner. It is sorted according to earnings per day.
