You're talking about holding the temperature of the water, right? As far as containing the liquid, they're about equal...but a styrofoam or double-wall plastic cup would hold temp better than a glass cup which would work better than a single-wall plastic cup.

Glass or plastic what keeps water colder?
Metal - very good conductor of heat. Not a good insulator at all (Don't wrap cans in aluminum foil.) Glass - A little better resistor of heat energy transfer but still not great. Plastic - Depending on the exact material, plastic is probably your best bet. Especially if it's a foam of some sort; the air bubbles in the foam create barriers that heat energy has to cross to be able to escape.
Which type of cup keeps hot water hottest polystyrene plastic paper or metal?
paper

Water has a density of about 1.0, knowing this you can tell if an object will sink or float by calculating the objects density.
Plastic foam wood and paper are good examples of what?
conductors
Does metal or foam keep water hotter longer?
In general, foam is a better insulator than metal, and so foam would be expected to keep water hotter longer under most normal circumstances.
Glass or plastic what keeps water colder?
Metal - very good conductor of heat. Not a good insulator at all (Don't wrap cans in aluminum foil.) Glass - A little better resistor of heat energy transfer but still not great. Plastic - Depending on the exact material, plastic is probably your best bet.

Is foam a kind of plastic?
Foam is NOT plastic!
Why is plastic foam used to wrap hot water pipes?
to stop condesation of water from the surface of pipe.
For water in glass plastic or styrofoam cups - which will freeze fastest?
Assuming they are the same or similar shape and volume, water in glass would freeze first, then plastic then foam. Foam allows transfer of heat out of water more slowly than plastic and the glass probably has the highest rate of heat radiation of the three.
Why do foam cups insulate better than glass cups?
Foam lets extra cold air reach the water
What will insulate better a foam or plastic cup?
Foam will insulate better than plastic.
Is plastic or Styrofoam the poorest conductor of heat?
The answer to this question depends on the magic word NIC. NIC is short for non-intercellular. This means that the tiny cells within the foam do not connect with each other. The foam does not soak up lots of water. You can't blow air through it. A plastic foam which is NIC is a very poor conductor of heat - a good insulator. A plastic foam which is intercellular is not a good conductor, but it is nowhere near as poor as NIC foam. Its best use is as a sponge for soaking up water.
Can you eat foam?
Assuming the foam is from furniture stuffing, then the answer is no. Such foam is plastic and is definitely not edible.
Which type of cup keeps hot water hottest polystyrene plastic paper or metal?
paper
Which type of cups keep hot water hottest polystyrene plastic glass?
Polystyrene is a plastic. I think you meant "polystyrene foam", which would be correct.

What is the freezing point of a pillow?
For feathers, foam plastic, cotton ... all well above the boiling point for water.
