I don't know where you want to compare these dates on your frontend or in SQL Server.
But because you posted the question in SQL Server forum I assume you want to compare datetime there.
So the answer is NO, there is no need to convert them to anything when you compare them.
No matter what are Regional settings the result will be correct.
