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/ 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.
