I used and repaired those in the 1990s. System 7 was usable on those, to be sure, but I don't remember anything about it as "excellent". Everyone thought they kind of sucked. You could see the ghosting even then, and by the end of 1992 or 1993, IIRC, Apple stopped shipping passive matrix displays. e-ink displays are not even up to that standard of responsiveness yet. And, as you point out, modern software has higher expectations than the systems that kind of sucked on those old passive matrix LCDs.
