Did you ever use OS/2? It wins the crown IMHO because of the object-oriented nature of the Workplace shell. Things like the icons were functional objects that had code and data (and state) owned by them. Also, using Rexx as the scripting engine was a bold and great choice.
I did back in the v2.1 days, but it suffered from needing a bit more RAM and CPU; by the time the Pentium was widespread I had already moved on to Linux. I think in the v3.0 version it got faster and better.
