The tantalum capacitors made with powdered metal compressed into a sponge seem to be very good indeed. I am using them on my collection of SE/30's with good results. Older "wet" tantalums suffer the same problems as aluminum versions. If you're talking about gold based "supercaps" I doubt that they're appropriate for old Macs. They have maximum voltage limits of about 1 volt and require series assembly to get to 12 and 5 volts required on older Macs. They're being developed with the idea of powering electric automobiles.
