Insert Proc Optimization

I'm pretty new to creating Procs in Oracle, I'm coming from SQL Server. I have a procedure that is taking a very long time to run. It loops through about 15 insert statement for the amount of days between two dates.

My question is,
would the proc be better optimized using a loop like follows:

BEGIN
FOR v_data IN (
Select statement
)
LOOP
INSERT INTO TABLEA (EMP_GRP_NODE_SK, DESCR, LABEL)
VALUES (v_data.Col1, v_data.Col2, v_data.Col3);
END LOOP;
END;

or would it be better to just run the insert statement as follows:


INSERT INTO TableA(Col1, Col2,Col3)
Select statement;


Thanks,
I'd appreciate any help, and or suggestions.

as a general rule option 2 will be faster.
