What I mean by mental models: Some producers rely on their favorite DAW's workflow. I'd never tell someone to ditch the DAW they're more productive in.
This is not a judgement. I'm not implying you don't "get" Ardour. On the contrary, I'm endorsing your approach: choose the DAW that meets your needs.
I said Ardour had improved a lot for me. I never said it would work for you. My comment was for the benefit of other people here. Giving a counterexample to your experience. No DAW is good for everyone. Ardour doesn't work for you. It does work for me. And if someone's looking for a DAW, I think Ardour is worth trying. I wouldn't tell you to try it.
And you already know it doesn't work for you, so you don't need to try again. I support you in sticking to the tools that you're most productive in. Nothing is more annoying than someone dictating what tools you use to do your job.
