Pro Community seems friendly and is growing
Pro Engine AND Scripting are both C#
Since the engine is written in the same language as the scripting, there is no weird mix of technologies as other engines have.
Pro Supports Vulkan
Currently the only well known open-source game engine that supports Vulkan, and probably one of the only.
Pro Easy to learn and use C#
Pro Multiple Starter Templates
The engine comes packed with multiole example projects to help you get started.
Pro Free
Can be used for free until you hit a rather high revenue cap, at which point you have to pay royalties.
Pro Powerful C# scripting
C# scripting is really well made, comparable to Unity, but without any of the legacy cruft.
Pro Multiplatform
Supports most platforms, including Windows, Linux, Android, Nintendo Switch, ...
Pro C++ support
The entire core is written in C++ and it supports writing game code in C++. The interoperability between C# and C++ is also nothing to scoff at.

Has a very modern, performant and beautiful rendering backend.
Pro Supports multiple IDEs
Works with any text editor and comes with proper support for Visual Studio, VSCode and Jetbrains Rider.
Pro Excellent documentation
The documentation is well written, up to date and accepts improvements from the community.
Pro Great and extensible editor
The editor is both powerful and simple. My favourite part is how easy it is to extend the editor with custom magic.

The entire source of the engine is available on Github, though not under an open source license.
Cons
Con No terrain editor
Unless you like working on planes, there is no terrain support.
Con Editor is Windows only
Since version 1.7, Linux can be targeted for runtime. The editor for the engine is available only to Windows though.
Con Small user community
Unity and UE have a vast amount of user community.
Con Does not currently support Playstation or Switch games
Con Iteration may be slower than with other engines due to longer "build" times when certain changes are made
Con Shader system require's overhaul
Shader's are not easy to get to grips with and Stride's shader system. Needs overhauling for easier use.
Con New software
As is standard with new software, not all of the bugs have been ironed out yet.
Con Few plugins
Unlike more mature engines, there isn't a vibrant ecosystem of plugins yet.
Con Not open source
While the source code is available, it's not quite open source
Con Not latest C# version
It uses Mono and is still on some variant of C# 7.
Con No OpenGL support
It only supports modern APIs, namely Vulkan and DirectX. This means that it won't run on very old machines.
