I tried Cursor but I honestly didn't see a huge improvement over VSCode + Continue.Dev. Cursor is better at editing multiple files, and it's cheaper than using the API directly... But I prefer VSCode + Continue.Dev (for chat) + Supermaven (for completions).
Cline, on the other hand, is a whole different beast. It edit multiple files, run the program, checks the shell for errors, go back to the files, edit them, run it again, and even access localhost:8000 to check. It's incredible! But if you use the recommended Sonnet 3.5, it'll eat your money very fast.
I've been using Cline + 4o-mini for a few days. Sometimes it's magical; it's the first time I truly feel that I have an assistant. I tell it 'run, check for errors, and correct them' and I leave to grab some coffee.
The bad side: I got lazy and once I almost let it delete rows in a table because it misunderstood what I said.
I'm a skeptic, but this weekend I worked with Cline in vscode (using free gemini nano backend and free mistral backend via openrouter) and managed to make some progress on a flutter app I'm working on.
Flutter/Dart isn't something I'm actually familiar with though I have a lot of dev experience, so I was able to distinguish between poor advice and good advice from the agent. There was a good share of frustrating code deletion happening that required stern instruction adjustment.
For work I'd be concerned about sharing our IP and would want to be on an LLM tier that promises privacy, or maybe even a local LLM.
All in all I was more impressed than I thought I would be.
