Oh - sorry, wrong debate :p

I prefer o-rings. They sit in a groove and thus tend to provide better sealing. (think of this too - in the days of "OC'ing" cars, one of the things done to allow better sealing of the cylinder heads was the addition of an o-ring feature around the cylinders to prevent blow-out of the head gasket ) In most high performance areas, whether it be car engines, jet engines, or rocket engines, o-rings are the preferred sealing method.
