I've tried 'em. Can't eat 'em. They're just too... gritty. Not much real flavor to them, either. Plain white gritty mush. Yum.
OTOH, my mom inexplicably likes them. Every once in a while, when we're driving around in the South, she'll make sure to order a side of grits and she'll talk about how she was kind of craving them and aren't they great and isn't it such a shame that they're not available in the Northeast...
To each their own, I guess.
