I reach for awk when my bash-scripts get a bit messy, perl is/was for when I want to build a small application (or nowdays python).
But both perl and python require cpan/pip to get the most out of and with awk, I just nead awk.

Because you (or someone else) can run your Python later if needed, and have confidence the output will be the same.
Sure, there are some times when a one-liner is needed, and you can always put that one line in a document for others to run. I can think of many times when I was on-call and needing to grep some data out of logs that wasn't already in a graph/dashboard somewhere. When time is of the essence, or if you're really really sure that you won't need to run the same or similar thing ever again, even if the data changes. I even changed my shell to make up-arrow go through commands with the same prefix instead of linearly traversing command history because I had so many useful one-liners I re-ran later.
But as I've gotten more experienced, I've come to appreciate the value of committing those one liners to code as early as possible, and having that code reviewed. Sometimes a really useful tool will even emerge from that.
