My favorite DOS GUI was PC/GEOS / GeoWorks[1]. It was the GUI behind the interface on the original AOL CDs. It had a nice office suite that ran very well on even low end hardware of the day.
I thought it was far superior to Windows at the time, and never understood why it wasn't more popular. It too has been open-sourced and is actively maintained[2].
