Depending on what the use case is, (for me it's note taking, bit of math/equations, code snippets)

- Joplin Editor is nice (due to KaTeX), "cloud" syncing can be made to work, iCloud not supported though

- Quiver https://happenapps.com/ , is paid, but math/equations are supported via MathJax, iCloud is supported

Currently, Joplin works for me but Quiver is overall better.

Personally, for a long time Google Keep worked for me (although it has gotten a bit cluttered)

I tried Notion and OneNote but their mobile apps were just too annoying and clunky (reaching 200+ MBs) for the value they provided for my barely 2-3mb of notes

Currently I'm back to Google Keep with occasionally using Trello and Google Tasks

Evernote still the best yet lol
