At 50% effectiveness, and 8 lives on average (which is about the most generous assumption possible), you’re saving 4 lives. GiveWell lists the cost of a life at around a thousand dollars, so organ donation is probably no better than a $5,000 donation to them. The main advantage of organ donation is that, if you’re not doing cryonics, it’s an effectively free donation :)
Conversely, the $25K cost of cryonics saves at least a couple dozen lives, and that’s for the cheap-end CI preservation without standby. So cryonics will always be a tradeoff between “some change of giving myself extra years” vs “saving numerous other lives, but they’ll die off after a few decades”
