John J. GrilloThe PSA registry (including the SGC registry) is great for the hobby. I think all the positive choices apply to some degree. Some find the competition aspect of the registry fun and exciting and that's is a good thing if it adds enjoyment for the collector.
I personally like using both the PSA and SGC registry simply to showcase the various cards I have, to keep track of what cards I need to finish a set, and to correspond with other collectors who may collect the same cards as I do.
