In my experience, Gemini Flash has been the best at writing, and GPT 3.5 onwards has been terrible. GPT-3 and GPT-2 were actually remarkably good at it, arguably better than a skilled human. I had a bit of fun ghostwriting with these and got a little fan base for a while. It seems that GPT-4.5 is better than 4 but it's nowhere near the quality of GPT-3 davinci. Davinci-002 has been nerfed quite a bit, but in the end it's $2/MTok for higher quality output. It's clear this is something users want, but OpenAI and Anthropic seem to be going in the opposite direction.
