What is the difference between the Jedi and Pylance language server?

Question

I'm having difficulty understanding the differences between the Jedi and Pylance language servers. I want to use them to extract repository-related information, such as the location of a function definition and the project dependencies, using a language server client.

Could someone please clarify the distinctions between the two? I am interested in their features and key differences. I have spent a significant amount of time reviewing their repositories, but the information seems ambiguous and hard to navigate.
