In addition to the reasons other people mention, placebo is a helluva drug. If you believe the name brand is better, it may actually become more effective for you even if the active ingredients are the same as the generic.
Name brands only matter to me when it comes to chips, soda, cereal bars (like nutri-grain), and shampoo. Maybe some others I'm not thinking of. But drugs are def not on that list. The only time I ever requested name brand drugs was when I got a script for Klonopin I didn't need back when I was an addict and only because I thought it would be cool to have the pills with the little K cut out of the middle, because like I said, addict.
Liquid gels are absolutely faster acting than compressed powder. I buy both generic naproxen pills and name brand Aleve liquid gels so that I have two different available delivery mechanisms (and unit prices) for the same active ingredient, and I choose which to take (or to give my dependents) based on the circumstances at the time of use.
