I used to love Cinnamon Toast Crunch but I tried it again recently and it's just too sweet. Even moreso than most other junk cereals. Favorite junk cereals are Frosted Mini Wheats Chocolate Little Bites and Reese's Puffs. Reese's Puffs feel extra greasy in your mouth and leave little oil slicks in the milk. Gross but yummy.
I think my favorites are Special K Red Berries (it has strawberries) and Quaker Oatmeal Squares.
Kashi Strawberry Fields is good too and it doesn't have an ingredients list as long as my arm, but it's friggin expensive for a tiny amount of cereal. You get maybe 3 bowls out of a $4 box. Red Berries is similar but costs a lot less.
Funny thing I noticed, "Strawberry Fields" has both strawberries and raspberries, but "Red Berries" has only strawberries.
