DOS had a lot of great games and programs that worked very well. It took years to build up the ecosystem and the performance, graphics and other techniques.

While Windows could multi-task and had other features that were theoretically better, there was still some catching up to do with regard to available software. DOS was also more stable, until the NT kernel was integrated into Windows. Windows 3.11 was quite stable, but 95 and 98 had issues.
