> I build full stack web applications in node/.net/react, more importantly (I think) is that I work on a small startup and manage 3 applications myself.

I think this is your answer. For example, React and JavaScript are extremely popular and aged. Are you using TypeScript and want to get most of the types or are you accepting everything that LLM gives as JavaScript? How interested you are about the code whether it is using "soon to be deprecated" functions or the most optimized loop/implementation? How about the project structure?

In other cases, the more precision you need, less effective LLM is.
