Produces highly optimised end results. Easy to use and quick to learn. When you know how to produce an Android app you near enough know how to produce an IOS app.
The fact that there are subtle differences between writing for different platforms is a huge plus - those differences help optimise your code and they're really not difficult to wrap your head round.

The speed of answer topics is amazing.
Pro Many informative video tutorials
The tutorials help beginners as well as more experienced programmers grasping important concepts.

Cons
Con No longer supported (deprecated since 2018)
Starting with version 4.x, Xamarin rebranded MonoDevelop as Xamarin Studio, but only for the Windows version of the IDE.
Stable release
7.6.9.22 / September 21, 2018
Con Bad formatting
MonoDevelop doesn't offer much in terms of autocompletion and code formatting. Most of the time the automatic formatting that MonoDevelop does is annoying and not really compliant with C# guidelines.
Con The MonoDevelop version that ships with Unity is several versions behind
The version of MonoDevelop that ships with Unity is several versions behind the main MonoDevelop branch. It also gets updated very rarely so any annoying bugs that it may have take a lot of time to get fixed.
Con Java-dependent Desktop Development
Con Only for Windows
The IDE, while very handy, only runs on Windows. If you want to code on Mac or Linux, you have to install it on a virtual machine. But you can debug your app by running it on the target OS.
Con The documentation and examples and tutorials are not up to date
The documentation and examples and tutorials are not up to date.
Con For BASIC language lovers
Lots of people are not fans of BASIC-like languages. Enjoyment of B4X, may depend on having a background or affinity for BASIC.
Con Can still need deep knowledge of Java
Attempts to provide BASIC-like language that is more comfortable for a certain demographic of users, but various circumstances will still require knowledge of Java. "No free lunch".
Con Lack of B4W real Web app
Erel needs to make a real Web app designer.
