AI writing tools ranked by subject: STEM vs humanities vs business

Been meaning to post this for a while. I ran a bunch of tests and took screenshots of everything so you can see the actual results.\n\nHere is my methodology – I used the same 500-word essay across all tools. The essay was originally written by me for my English 201 class last semester. I made sure it was 100% human written as a control.\n\nResults were pretty eye-opening. Some tools that get recommended all the time performed terribly while a couple lesser-known options actually delivered.\n\nThoughts? I know this is a controversial topic but I think we can have a productive discussion about it.
