I've been exploring alternatives, but so far nothing has stuck. Last time I looked at OneNote it seemed promising, but the lack of tags (seriously?) was a showstopper. DevonThink Pro was interesting, but the Mac experience and UI is archaic to the point of being unusable IMO. Esp. the way that DT bakes a really terrible styling onto imported Evernote notes.
I'd love to hear migration success stories from those of you who've moved on.
(1) One example: Want to create or modify a table on the iPad app? Nope. Baffling.
