I've tried them all, and actually like most of them. Currently I am making my own hot cereal:

.25 cup soy grits
2 tbl flaxseed meal
1 tsp almond flour
1 tsp unsweetened coconut
1 tbl vanilla soy protein isolate
1/2 tsp cinnamon
1/4 tsp vanilla
splenda to taste
1.25 cups of water

Mix dry ingredients together first. Add vanilla and water. Mix well. Put in one-quart-size microwave safe bowl (smaller bowl will overflow). Nuke for 4 minutes. Can also be made in saucepan on the stove. Add cream to taste

Not everyone will like this, cause individual tastes vary. But I really love it. It has about 300 calories, 7 effective grams of carbs, and 14 grams of fiber. I make a bunch of servings at one time and keep them in zip lock bags, so I just have to add the liquid and throw in the microwave. Saves time in the morning.
