I would prefer a gift economy, as I expect that a gift economy would be both easier to implement and more efficient. A gift economy also would be less likely to fall into the classic trap of the central authority becoming an antagonistic class relative to producers.
That said, a planned economy would be helpful for getting production situated closer to consumers and for developing an infrastructure based on more local distribution. The current economic dependency upon giant container ships and cargo jets is suboptimal. Efficiency really is the name of the game, since production is already far more than sufficient to meet present needs. The reduction of waste coupled with the elimination of the overproduction of goods would be fairly easy to accomplish in a planned post-capitalist economy, which would meet immediate needs. If a moneyless planned economy could be built with mechanisms in place for it to be dismantled within a very brief time period (say twenty years), it might make for a practical transition stage to a gift economy.
