Scfm ratings are very similar on them, I've used rol-airs, they are awesome. I own an old Emglo Airmate and Emglo wheelbarrow, they won't die and are rebuild able. Same goes for Rol-air, parts are readily available. To me the only benefit of one over the other is the rol-air's come with a 9gal tank, not 8 so you have a little extra air capacity. I doubt you'll go wrong either way
