Pretty happy with Rytr:
-Ability to generate content using all of the options in the editor is great!
-UX is pretty good--better than Peppertype.ai, where you have to copy content, and click back and forth.
-Quality of output seems to be better than Peppertype.ai and a bit better than WordHero. I give Rytr the edge over WordHero because Rytr produces better outlines.

It seems like there aren't plagiarism issues after spot-checking a few outputs by Googling the outputs in quotes. I just wish there were more credits available but it's probably standard.
