Atenolol vs enalapril maleate. which is better?

It depends: It really depends on the medical history of the patient. Both are anti hypertensives, but they work in different ways. For people with diabetes, Enalapril may be a better choice, while those with heart disease are often on either or both of those medications. Efficacy wise, each patient responds to the medicines a little different, so it really depends on the patient.
