It's not sycophantic and has a much better "voice."

Not that I’m a friend of OpenAI, but ChatGPT has relatively fine-grained “personalization” options, and it was never sycophantic with the “efficient” tone for me. Rather the opposite, sometimes it seemed slightly indignant when I criticized it.

It definitely is sycophantic, but uses A LOT less emoji, lists and header-paragraph-header structure.
