Lines: 19 I have a turbo trainer and I have ridden one type of rollers. Some rollers are quieter than others but I feel that a turbo trainer is the quietest of all. Rollers have more moving parts and caused my whole house to resonate at certain rpms. Turbo trainers create a loud hissing noise but have no substantial low frequency components. Rollers are excellent at simulating a true bicycle feel and are best for spinning. It is hard to get strong on rollers but you can get a good cardivascular work out. Turbo trainers are good for working on strength because they provide large resistance at high wheel rpms. The bad thing about turbo trainers is they don't allow the bike to give (sway) when you pedal. This may cause big gear heads to hurt their knees more rapidly on a turbo trainer. Excessively large gears will take their toll on your knees eventually anyway though.
