I don't think there is a correct answer to that. There are wrong answers, however. The best anyone can do is explain the pros and cons and then you have to decide which fits the best.

RAD model
Rapid Application Design: Used to get an application in to a usable state as quickly as possible. However, much functionality may perform poorly and it would be difficult to update.

spiral model
I presume this would be an interative approach, essentially looping around and around until the product was right. Intermediate stages can go in to production even although only partial functionality has been provided.

waterfall model
The classic, however it has been widely discredited for not allowing mistakes to be rectified easily, especially in the later stages of the project.

prototyping model
Allows a prospective client to see how the final product will look without any real functionality.

bug and fix model
What even the best intentioned projects descend into when management starts to panic - and they almost certainly will start to panic at some point. This is the worst model of all as the developers are told to throw all good practices out the window in order to achieve a fast turn around time. The problem is that the more best practices are thrown out the slower the team is to respond.

Basically, any model will give you a useable result, if (and only if) you obey the rules and follow the model 100% to the end. However, I would either use the spiral model (improvement and extension over iterations) or any military-developed standard (e.g. the (http://www.v-modell-xt.de/[^]) or the US DoD STD 2167A, because they come from an environment with similar requirements (highest availability and reliability), though this is no guarantee if you deviate from what the model dictates.
