I was split between Hemingway and Grammarly and ended up choosing in Grammarly. Hemingway, IMO, makes your writing clear, but it also makes it incredibly boring. Grammarly has modular settings for formality, tone, friendliness, etc which lets me view grammar-based tips while preserving my personal writing style.
The audience, formality, and domain expertise settings definitely work. And the tone settings do actually give feedback on the lower-right-hand side of the text input box in the form of emojis (albeit still experimental).

That is not my experience. I ran multiple, longer paragraphs through it now, no emojis displayed.
