claude code is definitely...more proactive than aider with gemini or sonnet-4. claude code will just go and do a whole bunch of stuff, asking questions of you and of itself, even compared to aider in architect mode. it does seem to get stuck less often, too.
you can just use claude code with anthropic API pricing, so I'd suggest you just try it and see if it's better for you personally or not.
