C# Type Comparison: Type.Equals vs operator ==

I suggest that you read the excellent When is a Type not a Type? blog post by Brad Wilson. To summarize: a runtime type (represented by the internal type RuntimeType), managed by the CLR, is not always the same as a Type, which can be extended. Equals will check the underlying system type, whereas == will check the type itself.

A simple example:

Type type = new TypeDelegator(typeof(int));
Console.WriteLine(type.Equals(typeof(int))); // Prints True
Console.WriteLine(type == typeof(int));      // Prints False

The reason is simple: The two are functionally equivalent in this case and the latter is more readable.
