Often a well-crafted artefact is more reliable. The maker is closer to what they make, and they cannot help but use more expensive materials and techniques because of their attachment. They want it to be as good as it can be.
This means that the artefact can be more reliable, or trustworthy, than something made by cost-focused approaches like mass manufacturing.
Generally these well-crafted artefacts last longer, and require less maintenance. If the artefact is complex, there’s a good chance the maker will over-engineer it, or build in more redundancy than is needed.
