I've taken Benicar and Diovan in the past, and Benicar is the most potent and effective of the ARB's. Side effects are less with Diovan and Atacand but blood pressure control is not as good as Benicar. It's a double edged sword. Many doctors are switching their patients from Toprol to a new beta blocker called Bystolic, which is supposed to be much more potent in blood pressure control. With Bystolic, you can drop all other HBP medications and take this alone. Keep in mind, it's been a wonder drug for many, but others have the laundry list of side effects. Ask your doctor for samples. The pill is manufactured by Forest Lab's (Ireland).
