I’m not quite sure what the OP is looking for in examples that prove or disprove the point. There are numerous early personal computers with unique features that failed under the onslaught of DOS-based systems.
Beta videocassettes not only outperformed VHS, they were smaller. But Phillips outmarketed Sony and VHS became the standard.
WordPerfect, Bank Street Writer, et al, had loyal users and features that Microsoft Word didn’t, but Microsoft simply buried the competition.
