I'm fairly new to mining and have tried several pools. I'll throw my take in and then take my flaming.
Bitminter: tried it for one day and got fairly lucky made about 20% more than I would have made here, the stats are terrible in comparison to eligius, just wasn't my style.
BTC Guild: mined for a few weeks at first, but just wasn't getting a good return. The site is rock solid and Eleuthria is incredible at answering and explaining any and all questions. It's my failover and always will be.
That being said I think eligius has by far the best user stats, the fairest payouts, and by the way they have grown in the last months others feel the same way. When the site had troubles last month Wiz worked his ass off to get everything fixed all the while being accused of various baseless charges. At that point I changed my donation from zero to 3% split evenly over the available options. When I read in Wiz's post that the total donations for the coming month will be 2 BTC I was to say the least floored.
My favorite aspect of the stats is that they are there for all to see. Not one of the top twenty miners pays one crappy Satoshi towards the site and you can click on any random 100 users and odds are you'll only find one or two that donate. This is a disgrace and an insult to the founders of the site. When i read Wiz saying he had plans to invest the 2 BTC I hope he plans on using it to go out to dinner with his girlfriend. We are all using a service. If you had a coupon for a free dinner at a fancy restaurant would you leave the coupon and not tip? That 2 BTC a month is a joke for all the work people are putting into this site.
Why is Eligius growing so fast because of greedy miners who give nothing in return, sure we solve more blocks quicker, but in reality they won't leave because they're greedy and know a good deal when they see it. Maybe I'm wrong and they are donating a percentage directly to Wiz, and I hope they are he deserves it.
The last time we had an outage and Wiz worked all through the weekend and then some he setup a donation account for his girlfriend. I set one of my miners to the address and posted it here thinking people would join in and mine along. Not a one did, and after all the talk of donations a 5PH+ pool, the second or third largest takes in 2 BTC a month in donations, sad.
So here is my challenge to all the the members of the FSA (free shit army). Mine for Wizkid for a day I just set an Antminer to following
eligius.st/~wizkid057/newstats/userstats.php/1EdeTHebTtymUULE5bdjWzW1gbCJkP7aQH Do the same, show that you support Eligius and show the others that greed won't be tolerated. PS I have no relation to Wizkid.
