Ask HN: Which agentic framework/tool do you prefer and why?

For those who've implemented AI agentic workflows in B2B/B2C environments:

Which framework did you choose (SmolAgents, OpenAI Agents SDK, CrewAI, LangGraph, etc.) and why?

What tradeoffs did you weigh (e.g., simplicity vs. control, single vs. multi-agent needs)?

I’m especially curious about real-world insights like:

- Did SmolAgents’ minimalism (ideal for lightweight tasks) suffice, or did you need CrewAI’s multi-agent collaboration (role-based workflows)?

- For OpenAI’s SDK users: Was tight ecosystem integration worth vendor lock-in risks?

- How critical was state management (e.g., LangGraph’s DAGs vs. AutoGen’s async chat)?

Thanks for sharing your experiences!
