Coach to shangri-la. Please advise.

There are two bus services to Shangri-la, one from Lijiang Transport Service Center Bus Station located at Changshui Road , the other from the Express Bus Station at Shangri-la Avenue.

What I would like to know is what's the difference between this two bus services other than they are located at different parts of LJ City. So which is the better option? Thanks a lot for the help in advance.
