Cursor was one of the first AI editors I used, but recently Aider has completely replaced the AI assisted coding for me. I still use cursor but just as an editor, all LLM work is done with aider in the shell.
I'd added seperate design/implementation agents before that was added to Aider https://aider.chat/2024/09/26/architect.html
The other different is I have a file selection agent and a code review agent, which often has some good fixes/improvements.
I use both, I'll use Aider if its something I feel it will right the first time or I want control over the files in the context, otherwise I'll use the agent in Sophia.
I tried using aider but either my local LLM is too slow or my software projects requires context sizes so large they make aider move at a crawl.
