Just in case you missed this in my Prime Time thread...
You bring up an important point, lucidhaze. Although nutritionally oats may be better in some ways, a person's lifestyle must be taken into account. Likes, dislikes, schedule, etc. are fair considerations.
I like a bowl of grits for variety purposes, from time to time, with some protein like Low-Carb Grow! added after they cool a bit. I think that grits can certainly fit into a diet that focuses on variety (i.e. not grits every day but having other fast carb sources, too).
NOTE: often the instant varieties of hot cereals are a second choice behind the less refined stuff.
