Using SQL Server – which is the fastest or best practice method to use for date retrieval? Is there a difference?

CURRENT_TIMESTAMP is standard ANSI SQL, and so is theoretically one tiny little island of ‘don’t need to change’ amongst your thousands of SQL Server-specific lines of SQL if you ever need to move databases….
CURRENT_TIMESTAMP is part of the ANSI SQL spec. GETDATE() is a SQL Server-specific function inherited from the original Sybase code on which SQL Server is based.
They do exactly the same thing, though.
My vote is for
CURRENT_TIMESTAMP for ‘portability’ reasons i.e. why be SQL Server -specific when there is a direct SQL-92 equivalent?
PS why was it not named
getdatetime()? Now that SQL Server 2008 has a
TIME data type, we can hope to get support for SQL-92’s
CURRENT_TIME, at which point
getdate() could be potentially even more confusing.
Books Online tells us that CURRENT_TIMESTAMP “is equivalent to GETDATE()”.
