I write Python every day, but still use miller here and there. If I am doing a "simple" operation (eye of the beholder), being able to pipe it on the command line is great.
To do a comparable amount of manipulation in Python takes a lot more boilerplate (imports, command line arguments, diety-can-we-default-to-Int64 already?, etc), plus you have to ensure you have a virtual environment with correct dependencies. Which is more or less standard numpy+pandas, but a single executable tool to do some data workup is always appreciated.
I am never performance constrained, but I have been told that miller is one of the slower tools in this space, but I still reach for it do to its wide format support.
