I've been using Aider with Gemini 2.5 Pro. Very impressed by the overall quality when compared to 3.7 Sonnet. Only thing that sucks is the rate limits.

The developer experience with Aider isn't that great when compared to a full IDE like Cursor, but it's a great way to get started because it's a simple CLI tool that accepts commands.

After that you might decide to switch to Jetbrains AI since you use Pycharm.
