I'll go against everything that I have ever been told and begin with the conclusion. The plastic or resin cage is lighter weight and typically will not set off metal detectors. It is also more resistant to changes in temperature and this typically makes it more comfortable for the wearer. Cracking, snapping and wear and tear is going to be a bigger deal with plastic cages. You should inspect these cages more frequently for cracks to ensure that he doesn't get his bits and pieces pinched.
I am also grouping silicone into the plastic category, these cages are more flexible than plastic but offer many of the same characteristics of that material. Silicone is a great option for active guys who run, cycle or have jobs that require frequent bending and stretching.
Metal or more specifically, stainless steel cages are much more secure, heavier and have a much higher appearance of safety and security. The heavier weight also creates a higher perception and reminder of being locked. The cold steel against his body is a greater reminder of my secure grasp on his most nether of regions.

If he is more active, a silicone cage is probably the right choice. If he is more sedentary or need a greater level of reassurance then I highly recommend the stainless steel cage. The sound of metal, the coldness of the touch. All of these things make the metal cage most appealing from the standpoint of the non-wearer.
Plastic cages come in all different sizes and are the most colorful of the bunch. The bright colors of plastic cages are typically the least intimidating and most fun for the couple that is just experimenting or trying to spice things up. If you are just looking for some bedroom play and overnight wear, the plastic cage is a great option. For the most part, this has been our choice because of the low cost and plentiful options.…
