Use Click for any CLI tool you're distributing or that has more than 2-3 arguments. It's the standard choice for Python CLIs, especially when you need subcommands (like git-style interfaces), prompts, progress bars, or colored output.
Use httpx when building FastAPI or asyncio applications that call external APIs. Also reach for it when you need HTTP/2 support, a requests-compatible API with async support, or a single library that works in both sync and async contexts.
For extremely simple one-argument scripts, argparse or even sys.argv is fine. If you want type hints to drive the CLI automatically, look at Typer (which wraps Click under the hood).
For simple synchronous scripts where you already use requests, there's little reason to switch — requests has a larger ecosystem of auth libraries and middleware. For high-volume async scraping at scale, aiohttp's lower-level control may be more efficient.
