Pros
Pro Multiple Platforms (Windows, Linux, macOS, Android, Firefox, Chrome)
Turtl has applications for all the major operating systems, as well as Android. In addition, there are extensions available for Firefox and Chrome that cooperate with the downloadable applications.
Pro Open source
The app is licensed under GPLv3 making it open source. This means that anyone can use the code and contribute. This also makes it easy to use on one's own server or for company solutions.
Pro Good security
After assigning a password to your account in Turtl, a key is created to encrypt the entire account. No data is stored on their servers meaning they have no access to unencrypted content. This is a huge leg up when comparing to other Evernote alternatives.
Pro Open source
TagSpaces is free and open source making it easily extendable with the help of extensions.
Pro Your can choose your cloud file storage
Using only files and no databases let's you make the decision with which cloud file sync service to use, making sure your notes are made available on other devices and platforms. It works great with Owncloud, Nextcloud, Dropbox or Google Drive.
Pro No web service or database lock in
The backend is simply the directory and file structure on your harddrive.
Pro No cloud
TagSpaces is running completely offline, sending no data to any cloud based service, unlike many Evernote alternatives.
Cons
Con No iOS app
While many other operating systems have a client, iOS does not have one yet (though it is planned).
Con No image embedding
Instead of image embeddings, there's a sort of poor man's substitute: image + description. If you add an image, you can create a description of any size and with all the formatting features. It can be used instead of image embedding but much more limited: only one image and only at the very top.
Con Internet dependent
Requires Internet connection to initiate offline mode, loses access to notes without Internet or server.
Con It renames your files in order to tag them
The positive side of this drawback is that this way the tags are easily transferred to other platforms by simply syncing them.
