What is more optimized way of writing delta table in a workflow which is running every hour, "append" or "overwrite"?

There's no "optimized way", as these are two different concepts, and depend on your use case: Overwrite  removes existing data, i.e. replaces it with new data, while append adds new data to your existing table.
