I have thought about this recently too. Here's my comparison and thinking. Wiki 1. Designed for editing by multiple users concurrently - think teams 2. History of changes 3. Structured and hierarchical 4. Latest versions like Confluence include Social features such as Activity Streams Evernote 1. Personal notebooks and notes 2. Selective sharing & co-editing by others 3. Tagging 4. History for Premium users You can allow others to edit even if they don't have a Premuim account, you have to have one and their changes are applied to your account usage. Two things that make Evernote difficult to replace a wiki, one, no social features like activity streams or discussions associated to a note (hope they don't get distracted by this and add it). Second, merging is manual when two or changes occur especially when someone is performs offline editing and syncs. What I do like and is also available in most good wiki's is search capabilities. Both wiki's and EN do this extremely well and if you use Tags on your notes, it's easier than having to think about wiki structure, hierarchy, linking, and indexing. I have used EN to share lots of notes (mostly from clippings via iPad or pfd's from external sources) with a number of people. In addition, have also co-edited a note all with personal premium edition. The Business edition makes it even easier; so, if you look at that version, now you might have a closer match. Also, if your company is super security sensitive and/or data is confidential, an on-premise wiki may be better. What you can't beat EN for is all the device support and all the various methods to add content - I love it. Just started using Postach.io with Evernote for blogging too, really simple and all blog posts stay in EN.
