Thanks to breakthroughs in ROSLYN compiler and the efforts of the .NET COre developer team, code written in C# can reach speeds just a step behind C++.
Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Comes bundled with a code reload tool
Revel comes bundled with a code reload tool which rebuilds the project on every file change. This code reload tool is also used to run, build and deploy the Revel application that you are building.
Pro Good examples easy to understand with simple emulated MVC behavior
Pro No need to find and install external libraries
Revel is a "batteries included" web framework, which means that a lot of features already come out of the box. This way you don't have to spend time and find third-party libraries to integrate to the framework for most of the tasks you need to complete.
Pro Easy to learn for fast development
Pro Fast and getting faster
Thanks to breakthroughs in ROSLYN compiler and the efforts of the .NET COre developer team, code written in C# can reach speeds just a step behind C++.
Pro Multi platform
Can run on Windows, Linux and Mac (also Visual Studio Code editor).
Pro JSON optimization
In .NET Core 2.1 and 3.0, new APIs are added that make it possible to write JSON APIs that require less memory, using Span<T> and UTF8 strings, and improve throughput of applications like Kestrel, ASP.NET Core web server. See also Utf8JsonReader.

Pro Ease of Use
Pro Security
It is a very secure platform.
Pro Tooling
Both VS and VSCode are powerful free IDEs that are well integrated with ASP.net Core. VS Community also allows for commercial use for projects with less than 5 developers.
Cons
Con Non-idiomatic code
Con Outdated
The world has moved past its MVC obsession. It's not the way the web works anymore. The good thing about go is that it's trivial to write a server applications (literally takes minutes). relying on a bloated, archaic framework is missing the point
Con Dead
Thankfully, this abomination is no longer being developed
Con No official support for mongo
Revel does not come with any support for MongoDB, you can integrate third-party libraries but they have been reported to crash under heavy load.
