I like Cursor, it seems very good at keeping its autocomplete within my code base. If I use its chat feature and ask it to generate new code that doesn’t work super well. But it’ll almost always autocomplete the right function name as I’m typing, and then infer the correct parameters to pass in if they’re variables and if the function is in my codebase rather than a library. It’s also unsurprisingly really good at pattern recognition, so if you’re adding to an enum or something it’ll autocomplete that sensibly too.
I think it’d be more useful if it was clipboard aware though. Sometimes I’ll copy a type, then add a param of that type to a function, and it won’t have the clipboard context to suggest the param I’m trying to add.
