Langchain vs Claude Agents SDK: which AI agent framework is best?

Description

I saw the Claude Agent SDK and Strands Agents SDK and thought... "this is going to simplify everything". Way fewer lines of code, built-in orchestration, no more managing context passing manually. So I ripped out my LangChain-based agentic workflow and replaced it with the SDK-based approach... twice. Less code? Yes. Same quality output? Not even close. It's also interesting to note that the same orchestration which Claude Code is built on ends up with way less fidelity on tasks like generating software architecture than custom-built agents. Here's my experience with these three frameworks and what I learned about them.
