Any advice on picking a Python language server for emacs? (programming.dev)

Hi, folks!

I'd like to set up my emacs with lsp-mode and lsp-ui, but I am finding myself in some analysis paralysis. Ruling out the Palantir language server because it's deprecated and because it's Palantir, that still leaves me with five language server recommendations from lsp-mode.

Anybody have any opinions they'd like to share? Any really bad experiences I should avoid? How do I configure your favorite? (Feel free to assume I know very little about configuring emacs.)

If it makes a difference, I am a poetry user and a religious mypy --strict user.

Thanks in advance!

That seems like a weird dichotomy between ruff and Jedi. One does linting & formatting, the other code completion, goto-definition, refactoring. With pylsp you can have both: it uses Jedi (in the default config), and has a plugin to call ruff for linting and formatting (according to the doc; I don't actually use ruff).
