I don't know any technical facts or have much experience with more monitors, but I've had one C1084 for some time and tried one CM8833 with intention to buy it if it'd been better. I didn't buy it, because in my eyes C1084 looked better by picture quality and outward appearence too

CM8833 had bit unfocussed colors at some parts and crt looked more rounder... also the power switch was in difficult place at back of the monitor.
