The OS/2 WARP Presentation Manager was a better "desktop" paradigm than Win3.11. It supported more customization and stranger "objects" you could store on your desktop. It felt a bit more coherent and a lot more powerful than the Win3.11 Program Manager.

I was mostly a kid with a huge stack of PC games I'd play, and OS/2 was a better launcher for many (but not all) of them than DOS/Windows. I was "dual booting" OS/2 WARP and DOS/Windows, but because of my gaming habits it was more like quintuple booting because I had a long boot menu with I want to say 4 to 7 different combinations of AUTOEXEC.BAT/CONFIG.SYS settings depending on type of game I intended to play or if I was going to use a Windows app or something else, then one OS/2 WARP boot option.

A bunch of Windows apps (many of which ran better, even) and even some games I recall I started launching from OS/2 WARP instead of DOS/Windows, making the first boot choice of the day a lot easier. (Though I don't remember being able to delete most of the other combinations, still had to reboot for certain games and Windows apps that needed more RAM than what OS/2 left for applications. OS/2's biggest problem at the time was a huge RAM footprint compared to Win3.11, much less DOS micro-tuned with AUTOEXEC.BAT/CONFIG.SYS low footprints for specific driver combos.)
