air strut or cyclinders?

Have anyone ever had experice with both setup? i have cyclinders right now and need to be replace and thinking of going air strut. Do they ride the same as cyclinders?,and how long do they usually last before it give out. Thanks

let us know what type of car they are on. bag struts usually ride better and are more expensive, cylinders lay out better, jut my opinion. if its a car it should be juiced.
