I have read that P2P profits long term are greater, does this still hold true?
Nobody can answer that, since it depends so much on luck and other factors. With the luck taking a very long time to average out, so the other factors a are really hard to measure. Over the past few months p2pool has had fairly bad luck. Very recently luck has been a little better. The future, nobody knows.
However, I will say that the expected value of the p2pool payout method (if set to zero fees) is higher than the expected value of the eligius payout method for finite time. Maybe that is important to you.
