Merge with insert selection selection

Question

Merge with insert selection selection

Which query improves the performance of Query1 or Query2,

Query1 uses the merge operator, Query2 uses the standard option Choose how to insert the update.

I could not decide, because the Merge operator uses as a side comparison, Side 1: Table 1> TAble1_Temp Side 2: Table1_Appliance> Table1

Standard selection compares data on one side Table1_Temp> Table1, (exists or not)

Thank you for agreeing.

Query1

MERGE Table1 AS T
USING Table1_Temp AS S
ON (T.col1= S.col1 and T.col2= S.col2) 
WHEN NOT MATCHED BY TARGET
    THEN INSERT(col1, col2,col3,col4,col5,col6,col7,col8,col9,col10,col11) VALUES(S.col1, S.col2,S.col3,S.col4,S.col5,S.col6,S.col7,S.col8,S.col9,S.col10,S.col11)
WHEN MATCHED 
    THEN UPDATE SET T.col3= S.col3,T.col4 = S.col4,T.col5=S.col5,T.col6=S.col6,T.col7=S.col7 ,T.col8= S.col8,T.col9= S.col9,T.col10= S.col10,T.col11= S.col11
    ;

Query2

UPDATE
    Table1
SET

    col3 = Table1_Temp.col3,  
    col4 = Table1_Temp.col4,  
    col5 = Table1_Temp.col5,  
    col6 = Table1_Temp.col6,  
    col7 = Table1_Temp.col7,  
    col8 = Table1_Temp.col8,  
    col9 = Table1_Temp.col9,  
    col10 = Table1_Temp.col10,  
    col11 = Table1_Temp.col11,  

FROM
    Table1
INNER JOIN
    Table1_Temp
ON
    Table1.col1 = Table1_Temp.col1 and 
    Table1.col2= Table1_Temp.col2




Insert Into Table1(col1, col2,col3,col4,col5,col6,col7,col8,col9,col10,col11)
Select  col1, col2,col3,col4,col5,col6,col7,col8,col9,col10,col11
        from Table1_Temp S  Where  not exists 
        (Select * from Table1 where S.col1 = Table1.col1 and S.col2 = Table1.col2)
