BETWEEN clause -- faster or slower SQL Performance?

My experienced mainframe DB2 colleagues have warned me that coding the predicate "WHERE part_no IS BETWEEN :foo AND :bar" is less efficient than "WHERE part_no >= :foo AND <= :bar"

Is there truly a performance difference?

With DB2 UDB for iSeries there is no performance difference between the BETWEEN predicate and its logic equivalent.
