CygnusEd was first released in 1987. I don't think it's fair to compare with a modern editor that was released 30+ years later.
I have not used either [1], but their choice was based on what was available at the time.
Edit: [1] Actually I did use CygnusEd for simple text editing, but I was not into programming at the time. I don't have a basis to compare it to modern editors, other than the knowledge that choices needs to be seen in the proper context.
