When I had both the Senco and Bostitch they seemed close to each other in volume of noise with the Senco being maybe a slight bit quieter. I think Bostitch rates the CAP-1512 at 80db. The Rol-Air is much quieter than either one (72db), but almost 2x the weight. Both the Senco and Bostitch are very easy to transport. The Rol-Air isn’t too bad but I much prefer to carry the Bostitch up any stairs. (22lbs)
