So I view a difference here between choosing a tool and designing a tool.

As a user/consumer, sure, you mostly decide pragmatically. Though values do come into play. For instance, if you value extensibility over approachability, you might be ok choosing a more complex tool even if it is more difficult to use at first.

But if you're building or designing a tool and you're making trade-offs, your values end up defining what you design and build.
