I think you can divide (useful) experience into two components: 1) a person's maturity as a programmer / team member, and 2) their level of practical knowledge with a given technology stack or your problem domain. I think that maturity is undervalued in this industry and is a must-have for senior developers. For practical knowledge, it can be extremely helpful to have someone who knows where the bodies are buried in the tech stack you are using. However, if you already have the knowledge on your team, then getting someone who can pick things up quickly might be a better focus.
