I guess I'm nobody, because I certainly chose Win95 over OS/2.
After being forced to use Win3.1, I jumped to OS/2 as soon as was possible. I ran it for three years, hoping in vain for IBM to fix the bugs (specifically the input queue), and waiting for various vendors to start releasing things other than bare-bones, feature starved applications. And waited, and waited, and waited.
When I got a new PC in March 1995, I spent seven weeks struggling with drivers, trying to pry support from IBM and various vendors (I'm looking at you, ATI). Then I got a peek at the Win95 beta. In comparison, it slid in like butter - my printer worked, my video card was now showing 1024x768 rather than 640x480, and even my tape drive worked. I figured I'd switch back OS/2 once IBM caught up and achieved feature parity. I guess I'm still waiting.
