CONCAT() function advantages

Why should you use the new CONCAT() function?   2 good reasons:

1. When using the CONCAT() function, non string datatype arguments can be included and are implicitly converted to a string datatype.   Using the traditional “+” to concatenate fields, all of the fields concatenated needed to be of the same data type.   Using the concatenate function reduces coding time as there is no need to convert datatypes.
2. The CONCAT() function automatically handles NULL values.  If a concatenated field contains NULL, the function substitutes and empty string of type varchar (1).

The CONCAT function was introduced in SQL Server 2012.
