The gel-filled rests may seem softer and more flexible since they provide cushioning to support your wrist, similar to the way a pillow cushions your head. Memory foam is designed to contour to the shape of your wrist and relieve stress at pressure points and retain body heat, thereby increasing blood flow and is seen by some as more ergonomically advantageous. Since memory foam molds to the shape of your wrist it also keeps your wrist in a more fixed position so it may seem less flexible. Actual softness will depend on the quality of the rest as well as the thickness of materials and the material used for the covering so you may encounter lower quality gel-filled rests that seem stiff. Keep in mind that if the wrist rest is too soft it won't provide effective support so if you need ergonomic benefits for a wrist condition or strain, memory foam may be a better option but if you're simply looking for cushioning and comfort, a gel-filled rest may be more to your liking.
