Pool efficiency

[Coma]

Is it possible that a pool might be more efficient mining than other?

I mean, deepbit charges a 3% fee. But if it's 3% more efficient than any other pool, it should be theoretical the same to use a no-fee pool than deepbit.
But what if deepbit is 5% more efficient?

theoretically all mining has the same chance any pool or non pooled mining rig in the end should all payout the same. the only way a pool can be more efficiently then another pool is by having better coding and network setup. if you get a lot of stale shares in a pool then you should switch to another one.

Better coding is what I'm takling about.
But does this only reflects on stale shares?

If a pool gets a lot of invalid blocks (say, the coding causes the pool to tell other bitcoin nodes about a found block only after a 120s delay, or it is connected to the network in a bad way) but doesn't pay for them, that's also less efficient.

I don't know a pool where this is a problem though, so..
