If something works and as long as it is not such a crucial part of your life and its a matter of life and death, you can (in many cases) always go with what has worked previously. One other argument can be the cost benefit analysis of the research itself. The time and energy (which ultimately translates to money in some sense) you put on research may not be worth the feature(s) one option offers over the other. You may never use that feature or in case of price, how much you may have to more for the brand you are loyal to may be less expensive than the risk you take by going with an option which you yourself have not tested first hand.
