Tried and true may seem boring. But as you said, if it works, use it. I always feel like picking the right tool for the job is the correct approach. Sometimes this may be a new framework. Sometimes it may be a new API. But it's not always the case. I work with what most would consider an outdated stack, even though it's less than 4 years old, a lot has changed and technical debt piles up.
In my opinion, it's better to be able to get a new developer up to speed quickly rather than spending more than a month or two getting a new developer to where they are able to make significant contributions.
