My code editor of choice (Helix) doesn’t support integrations or plugins so I haven’t tried Cursor or Copilot. I’m building my own UI right now that focuses on first-class support for models served by llama.cpp.

As far as self hosted models go, deepseek-coder-33B-instruct is the best model I have found for coding. Anecdotally it seems more coherent and gives better results than Phind-CodeLlama-34B-v2.
