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 Note encryption
Pro Free and open source software
Pro Excellent WYSIWYG interface
Pro Attributes that can be assigned to nodes and inherited
Pro Graph of node connectivity
Pro Note versioning
Pro Synchronization with a server
You can set up synchronization but you need a server to do this.
Pro Database storage rather than files
This enables the tool to do a lot of things that would be difficult with plain text file storage.
Pro Archival functionality
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 Interface can be confusing
There is a fair amount of flexibility to the interface but it can also become confusing, especially when some parts are not necessarily simple to use. Most of the basic features nevertheless are intuitive.
Con Database storage rather than files
This makes it a little less simple to work with (also has benefits).
Con Not markdown
It will import and export markdown but it does not store content as markdown. This isn't necessarily a problem if you don't need it.
Con Synchronization requires use of Trilium's sync server
This can be problematic to set up unless you have a web server that will support the requirements of this.
