were you immediately more productive in Cursor specifically?
my point is exactly inline with your comment. The tools you get immediate value out of will vary based on circumstance. There's no silver bullet.
I use Aider, and I was already quite good at working with AI before that so there wasn't much of a learning curve other than figuring out how to configure it to automatically do the ruff/mypy/tests loop I'd already been doing manually.
They key is that I've always had that prompt/edit/verify loop, and I've always leaned heavily on git to be able to roll back bad AI changes. Those are the skills that let me blow past my peers.
