+ Startup and typing latency are far lower than any Electron-based AI editor.
− Extension ecosystem is small compared with VS Code and Windows support only arrived in 2025.
+ Tab autocomplete predicts multi-line edits across files better than any competitor.
− Usage-based pricing changes and request limits on Pro have repeatedly frustrated heavy users.
+ Deepest GitHub integration: assign an issue to Copilot and it opens a PR.
− Completions and agent lag behind Cursor and Claude Code in quality despite more models being offered.
+ Works with local Ollama models or any API, with fully customisable config.
− Setup is more fiddly than Copilot and autocomplete quality depends entirely on the model you choose.
+ Cascade keeps context of what you just did in the editor and terminal without being told.
− Ownership turmoil in 2025 (OpenAI deal collapse, Google, then Cognition) caused model-access gaps.
