Note that Aider is not much maintained over last 3 months or so, there is a fork Aider CE, though I'm just watching their changes through rss and not used myself.

I'm more in Opencode world now and its in general more efficient for me (I'm sorta sysadmin by day, not a programmer, so agentic mode with Opencode saves a lot of time cuz you can just tell - write adhoc Python script and check which objects/methods present at that library- savings me from a boring part of you know programming/diving deep in unknown languages).

On Aider part, I especially liked ability to nitpick the function name, which is great for more focused changes/investigations.
