On the other hand, I think MS are pretty much cloning the good stuff from Cursor, like agent mode: https://www.youtube.com/watch?v=dutyOc_cAEU
Leaves me thinking VS Code might be the best in the long long run, but for now they're all kinda similar?
Isn't the situation similar to Brave et al built on top of Chromium but supports Chrome extensions?
There are open source alternatives, the basedpyright extension is better than Pylance and I've heard the clangd extension is good.
For completion models: no, they retired gpt-35-codex, leaving only 4o-copilot.
From my experience (GH Copilot Pro with engaged_oss SKU, ie. for free), after they announced their "pricing changes", they also made the performance worse. The completions went from good, to actively distracting. tldr; they enshittified it / did a rugpull.
Right now, it is not worth paying for. ChatGPT Plus is far better value for money if you don't care about autocompletions/pure vibe coding.
Maybe Cursor/Windsurf could've just been plugins? Only Zed.ai seems really different of the popular IDEs
