Can you elaborate on this?

I have a proof-of-concept RAG system implemented with LangChain, but would like input before committing to this framework.

LangChain is considered complicated to get started with despite offering probably the widest amount of functionality. If you are already comfortable with LangChain you are free to ignore that.
