What are your requirements? For example, I use Squid (formerly Papyrus) more than LectureNotes because it's better for annotating PDFs, which is one of my major uses. But I don't use OneNote or EverNote, so don't know or care about sync with those. Hence my requirements and yours differ.
So if you tell us what functions you need and what you use it for it will be easier for people to help.
