I think you're dealing with three different functions and accessing one of the three in two different ways. 1. File > Open With allows you to choose an application to open the selected file on a one-time basis. 2. (Option) File > Always Open With allows you to set the default application to open the selected file. 2 a. Get Info > Open With does the same as 2 above. It allows you to set the default application to open that single selected file. 3. Get Info > Open With > Change All allows you to set the default application for all files of the same type as the selected file. (Keep in mind that you might get a pdf that is not seen by the OS as a the same file type as the ones you selected Change All for, and may have to set that file type too.)
