A human could write either. The former is just slightly more formal and concise.

Before AI, I used to write everything in somewhat formal phrasing mostly because I enjoyed it and a tiny bit because I assumed (perhaps incorrectly) that it made me sound smarter. Post-ChatGPT, I noticed that most LLMs had a writing style fairly similar to my own, so I changed my writing style to appear less formal in most circumstances. While I'm not anti-AI, I'm always fearful of being mistaken for a bot.
