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 Publish and share notes
Publish notes to the web (with configurable URLs) or share notes with collaborators.
Pro Offline-first
Fully functional offline mode.
Pro Omniplatform
Can be installed on macOS, Linux, Windows (via PWA), iOS and Android.
Pro Task/calendar syncing (Google Calendar & Outlook)
Any task with a date/time assigned to it will be exported to calendars optionally connected. Completing the task removes it from calendar.
Pro Multi-level tagging (personal/hobbies/bike-rides) to keep organized
Any note can be assigned as many deeply nested tags as desired. The tag hierarchy can be navigated, filtered on tasks or notes.
Pro Backlinking & networked note references
Amplenote supports the same [[]] syntax popular in Roam to create a link to an existing note. Every linked note has a tab with all the references into that note.
Pro Automatically sorted task list
Every task can be marked as "Urgent" or "Important," along with the time it's due. This makes it possible for the software to automatically sort your todo list in a way that makes sense, and save you time of deciding what to work on first every day.
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 Not end-to-end encrypted
