PC monitors with RGB were a different ballgame, at least at that low resolution there was no distortion or bluriness as you say. Even PCs had games for composite video: https://youtu.be/niKblgZupOc?t=504

TVs though, especially on RF, were pretty darn blurry.

Oh, maybe i stopped before making a point. Even those high end CRT monitors still had free horizontal anti aliasing and pixel characteristics that made the image be perceived differently from how it looks on a LCD.
