I use Deepbit's proportional mode, lesser fee and higher profit over time than deepbit's/btcguild's PPS.
Good for you but still that's 3% fee for the most primitive, proportional payout scheme.
What about classic proportional mode nowadays on other pools, it isn't that good anymore because of pool hoppers?
You'll be a sheep the pool hoppers thrive on. If that doesn't bother you, be my guest.
As I said SMPPS, PPLNS, PPS, and DGM payout schemes were invented with the explicit purpose of being immune to pool hopping.
No payout scheme should influence your revenue in any way. Some being more variance than others but all the differences average out over time.
The only things which really matter are pool fees and stale share percentage.
Some pools introduce fancy features to lure users: Triplemining has a 1 BTC jackpot every week. The only problem is, being one of the pool's 130+ active users there is no reason you should expect to win the jackpot this year. As I said, it's more of a lure than a tangible advantage.
