Definitely the space I'm in, where I know exactly what I need, exactly how to implement it, just saves time typing 100s of lines.

Yes, the third camp and probably the most effective is to do a decent amount of writing yourself and use the LLMs as codegen machines, but where the DSL is natural language. Deepseek v4 flash is an incredible model for this, you can actually get into flow state as you write code and then delegate boring code to the magic autocompletion machine to autocomplete.
