I think of it as a trade-off between the tool perfectly designed for the job and the tool that can be used for the job of which I'm already an expert user.

As an example, my current team's codebase is Python and C++. When we need to do some basic Linux scripting (check if this file exists, if not send an error email), the two prime candidates are Bash and Python. Bash might be exactly designed for this type of thing, but a lot of the team would need to Google stuff like "bash logical and of two booleans" for Bash where they already know the Python syntax. My current rule of thumb here is "<10 lines of code: use Bash. else use Python". More generally, I often try to err on the side of using the tool I know than the unknown tool that might be perfect for the problem.
