Hi Mikey604,
I don’t have any personal experience with either pillow but the differences between them will really come down to two things. The first is any difference between the materials in each pillow and the second and most important is any differences between them in terms of how they feel and how well they keep your head and neck in good alignment in all your sleeping positions.
In terms of the actual materials … it’s not really possible to make a direct comparison because they don’t provide the information you would need to make these types of comparisons. It’s certainly possible that the formulation of the gel in each of them is different and/or that one uses more gel than the other one. It’s also possible that the specific design of the gel layer in one may provide more airflow or be more comfortable to you than the other one. Both of them also appear to use memory foam as the main core of the pillow and neither one of them mention the density of the memory foam they are using. Higher density memory foam would be more durable and is generally more costly but density isn’t directly related to the properties of the memory foam so you may prefer the feel or response of either one over the other.
In terms of how they feel or perform … a suitable pillow is an essential part of good alignment for the head and neck and upper body because the gap between the head and the mattress and the curve of the cervical spine needs to be supported just like all other parts of the spine. Like mattresses though … there are certain “needs” that depend on body type and sleeping positions (and on the firmness of the mattress you are sleeping on) but with pillows, personal preferences play a more important role because the face is much more sensitive to textures, temperature, smells, and other more subjective “feel” based properties of a pillow. There is more about choosing pillows in the pillow thread here and the other topics and sources of information that it links to that may be helpful as well.
Better sleep shops will often have samples of their pillows available for you to try (they should be in a pillowcase and not a plastic wrapping) so you can try different types of pillows and pillow materials in person and use your own personal experience rather than just “theory” or other people’s experiences to help you decide on the types of pillows and pillow stuffing you tend to prefer but the only way to know whether a pillow you haven’t tried before a purchase will work well for you will be based on your own personal experience when you sleep on it.
The soft solid gel in both of them would be a good thermal conductor and would have a cooler “hand feel” and would also be the layer closest to your skin (outside of the pillow cover) so it may be enough to offset the tendency of the memory foam underneath it to be more insulating and sleep warmer for some people. Some people also don’t like the feel or firmness of the soft solid gel but only your own personal experience can tell you how you feel about a specific pillow regardless of whether anyone else likes it or not.
Hopefully some of the members that have tried the pillows you mentioned will see your post and share their comments about them or about other similar pillows they have tried but it’s unlikely that out of the thousands of pillows on the market you would find a member that has tried both of the pillows you mentioned and compared them directly. Of course I would always keep in mind once again that their own needs and preferences or their experience on any particular pillow may be very different from your own.
