Most people that use copper gaskets do so because you can re-use them, and they will generally handle more boost than stock gaskets...

The disadvantage of coppers is that (as I have read in the past) gets "eaten" by water... any comments on that?

Copper roofs are the longest lasting roofs.....and they are exposed to water....
I just hadn't heard that before, but I've never used a copper gasket before...but know some drag racers that do....

FWIW, the true down side to copper gaskets is they tend to 'weep', or seep coolant until the engine is up to temp. Even fully annealed, they are not truly compressible. I ran a copper head gasket on my Toyota 22R w/supercharger 20+ years ago, and it was aggravating to say the least. There was always coolant leaking, and that was with ARP head studs and with an o-ringed block. Hylomar is supposedly the best thing to use to prevent or reduce the seepage, but I never tried it back then.
