I know its a noob question but I am new at it.
Trying to compare p2pool with any other pool after only 8 days is pointless & will only give you inaccurate & misleading information, hence your apparent confusion. In order to truly compare you should mine for a much longer period, then you will see the difference. P2pool is for people who understand & care about the future of Bitcoin & a decentralised network, so coming to this thread & telling miners to move to a different pool simply because you are impatient & don't understand the workings of p2pool won't work, you'd be better off spendinding your time reading up on the basics & digesting the facts.
If all you are after is a quick profit, quit mining & start buying/selling. The profit train left the mining station a long time ago.
