Quality towels are important for similar but different reasons than paint in this case.  You want optimal cleaning for glass.  You do not want a microfiber towel which you are chasing your proverbial tale.  You also want a large collection of towels.

Whether they fall under the category of glass cleaning or drying towels, very rarely can you go wrong with waffle weave towel for cleaning windows.  It is great at cleaning glass thoroughly without smearing grime.  My personal preference is the DI Waffle Weave Glass Towel.

Having some smaller than usual microfiber for intricate areas helps make your life so much easier.  Although the picture (below) shows one of the many 8′ by 8′ microfiber glass towels I own, Autofiber makes very good miniature glass towels.  Smaller towels made for cleaning sport cars score high marks in terms of user experience.  In lieu of trying to get into intricate areas, you are also trying not to rub your towels on to the surrounding surfaces that carry dirt, lint, and oils.

If I am not re-washing the entire car and I know the windows are very dirty, I will often use a coating towel for an initial wipe.  This makes the follow up (touch up) cleaning with a waffle weave towel that much easier.

I will also add the Autofiber Korean Twist 600 Towels have really grown on me.  It deserves honorable mention and consideration as a new favorite glass towel. Though I still believe a great turning point for me was the use of nitrile gloves when cleaning glass, to prevent my oily hands from working against me.
