It's the best I've tried so far. I only tried copilot when it came out, so it might have improved a lot since then, perhaps someone using both now can chime in.

There's two things I like about cursor - the overall multi-file edit -> I use this for scaffolding whatever I need, at a high level, and claude 3.5 seems a bit better than 4o for this.

The tab thing really works, and it will surprise you. They don't do just autocomplete, they also do auto-action complete so after you edit something, your cursor (heh) goes to the next predicted place where you're likely to make an edit. And it works ootb most times, and a few times I've gone "huh, might have missed that, if it weren't for the cursor going there".

So that's my current workflow. Zoomed out scaffolding and then going in and editing / changing whatever it is that I need, and cursor has two really strong features for both cases.
