Cursor include an agent that can write code for you, fix errors on its own. Copilot is mostly autocomplete.
Cursor is far superior at indexing files, i.e. knowing which part of the code does what. This is probably their special sauce. There's some codebases that it can't index and Copilot works better there.
Like IDE vs text editor, some people have different comfort levels on how much code is written by the AI. Copilot is lighter, Cursor is in the middle, and on the other extreme, you have Devin which you chat with like it's a person.
I personally like the Socratic nature of a ChatGPT conversation - copy pasting back and forth if I need to - as I’m more likely to learn to fill in gaps in my possibly hallucinated LLM derived knowledge
(assuming default configurations, and this was my personal experience in a 4 year old software project)
Copilot felt like an incompetent colleague you needed to slap to get anything coherent out of it.
Cursor feels like an overly eager junior colleague that wants to refactor everything. It works, sometimes it makes sense. Your project overall increases in velocity anyway.
I personally think it is very much worth it. But they have a liberal free trial, so you can find out for yourself if it is worth paying for your particular situation.
