There is common consensus though that nylon is the best material- probably because of its softness o the skin.
There is a common school of thought that the best panties for men are the full brief. This is for a number of reasons.
They provide enough coverage for men, more than others do and prevent bits slipping out of place and being uncomfortable.
They provide enough fabric to feel like they're there. Most women's underwear is small and there for doesn't feel like it's there and is just not as satisfying as it should be.
The fit is also quite snug which offers a nice firm secure feeling. Some men do prefer the loose fit as it is teasing and can add a nice feeling to wearing nylon panties but most like them for their snug fit.
They are also more hygienic, drawing sweat and unwelcome fluids away from the area. Thongs are not very suitable for men as sweat builds up and follows the way down the thong to other areas which can cause issues and is also just quite disgusting.
Most people asked will say they prefer the full panty made from nylon for one, a number or all of the above reasons.
However, as with everything in life there is a lot of people out there and a lot of preferences among those people. So there is little to say that anyone should like a particular type. Wearing panties is about expressing hidden sides of yourself, and the only one who knows how to do that best is you.
