I had to do it for work at some point in the late 90s and IIS did actually had a pretty good configuration application whilst Apache was all text configuration files.
The problem was that IIS compared to Apache was heavier, less performant and scalable, not as stable and it required Windows (if I remember it correctly it was even heavilly tied to other MS software such as their database).
Apache did require a bit more expert knowledge to get going, but in all else it was already superior to IIS.

I’m surprised anybody still uses IIS.
