Welcome to CD Freaks.
You already know the difference between the two–the Q has LightScribe, and the F doesn’t. That’s all.
Some are less than impressed with the write quality of the 22x drives in comparison with the 20x drives [S202/S203], and would prefer their S203 drives for writing over their S223 drives.
However, that’s not saying that there is anything really wrong with the S223’s writing quality [such as failed burns, unreadable burns at reasonable speeds, etc], just that other drives have done the same media better.
