Dissapointing only due to lack of sales and 3rd party support.
I was never dissapointed with the quality of major games on the system, just the lack of new quality games after the initial few years. Nintendo has had a problem working well with 3rd parties, and I think that is one major reason both of those systems had difficulties. That along with Nintendo's selection of lesser media on both systems (cartridges instead of cds, to a lesser extent GC disks instead of DVDs) played a role in both systems' dissapointments.
I would concider both dissapointments in some ways, but not failures.
