In certain applications pocket screws are superior to biscuits. I agree it is more about the pocket itself and the application of use rather than the actual screw. If the SS pocket screws were way expensive I would just use a similar sized SS pan head screw.
Biscuits....thatís the word I was looking for!
I agree soulsailor, screws may have some advantage, no clamps for one and having a real mechanical fixing that does not rely 100% on the glue could be worth while advantages.
