Gel or memory foam — which wrist rest is better?

Reviewers are genuinely split. Gel (often with a cooling layer) is praised in retailer reviews for staying cool during long sessions, while memory foam threads in r/MechanicalKeyboards note it conforms better and doesn't develop a sweat sheen. A widely-cited r/MechanicalKeyboards comment notes that after an 8-hour workday, there's no noticeable strain difference between a gel rest and a wood rest, so feel is largely personal.
