I'm happy with them. I prefer them primarily because they are stable while also being large enough that they don't have massive variance.
they are happy with you too... you give them 1.5-3% of your income. for what?
use p2pool and don´t support centralized mining!
Both parts of my "because..." sentence are important to me (I highlighted the second part for emphasis).
In any case, this is off topic from this thread and we can continue the debate via PM or in the p2pool/btcguild threads.
