The curriculum flowing from n8n -> langgraph -> crewai is quite natural and satisfying. After trying out all the agent frameworks, I ultimately found that crewai is the best. I use crewai for most of my projects, and I love how the approach allows me to learn step by step from simple single-agent projects to complex projects combining multi-agent and flow. Rather than simply using the tools and memory provided by the library, you teach how to develop them custom, which has been a great help in coding my agent ideas.
