Women, do you prefer a man’s black boxer briefs to be elastic or cotton and why?

Black boxer briefs are a clear favorite. However do you like elastic or cotton more on your man?

P.S. Assuming you’ve never worn both, from a guy’s perspective, cotton underwear is more breathable but they don’t last long before they lose structure around the legs and therefore don’t hug your body as well. Elastic will last so much longer in form but are just a tiny bit less comfy particularly in the summer heat.
