Pros
Pro Free/Libre/Open Source
Pro Cross platform
Code::Blocks is available for both Windows and Linux, allowing you to use the same IDE across both OSes if you use different machines.
Pro Easy to use
Easy to pick up, for example much easier to include libraries.
Pro Debugger multi-threading support
The debugger supports multi-threaded processes for faster debugging.
Pro Lets you choose the compiler
Code:Blocks lets the developer choose which compiler to use, giving you a higher level of control for on your development workflow.
Pro Free, and now with Xamarin support built-in to target most Oses.
Pro Visual Studio UI
Visual Studio set the IDE standard for most of the '90s. Although it has languished somewhat and some embarrassing UI defects remain in the Windows version, we can hope that Microsoft will deliver a fairly well-organized IDE for the Mac.
Cons
Con It's hard to make the code readable
Due to the problems with indention, it's hard to make the code look nice.
Con Poor code completion
The code completion for Code::Blocks is rather poor compared to other IDEs
Con Currently doesn't support C++
As of now, Visual Studio for Mac only supports .NET, C#, and F#.
Con VS doesn't support C11 for windows! mac will never ever see C support in there.
No wonder MS team hates C language - they've stolen from Unix so many things and Unix is still there :) Now mac 'borrowed'BSD - so for those stupid things buying mac ONLY, they will never promote free things.
