Sloppy, I tend to find fluffy obscures the model. I always like for them to be visible instead of just existing under the mess.

Sloppy. The thicker and stickier the better, especially if there is a nice oozing effect...

The pies by the user "Blaine" really hit the spot. Pie perfection right there, some with more ooze, and others with a slight bit of fluffiness to them. Unfortunately his last login was 2012.
