The one filled with water will be fastest, followed by the one filled with marmalade. The empty one will be the slowest.


This result may look strange at first, as one would think that the heaviest and densest jar will be fastest. At least at normal pressure when air is around, in a vacuum a feather would fall as quick as a stone brick, but that's a different story. 


Aside from the density, there's another effect of importance here. When the filled jars are rolling, the liquid inside will be stirring, causing energy loss due to the friction. Water will have less friction than marmalade, and thus less energy loss. Due to water's lower friction, it will remain “relatively” still inside the glass, whereas the marmalade is forced into more chaotic behavior. In addition, this behavior is not as energy efficient, contributing to the result that the glass filled with marmalade will be slower.
