Mw2 acr silenced vs scar h silencer?

Hey guys I've hard that both the scar h silenced and the acr silenced are great guns for nukes. I love both guns but which one should I use more? Or which do you think is better for nukes? My class for my acr silencer is acr silencer, AA12 grip, claymores, scavenger pro, stopping power pro, commando pro. My scar h silencer is this : scar h silencer, raffica FMJ, claymores, soh, hardline, and commando and my other scar h class is the same primary, secondary, and equipment, but perks are scavenger, stopping power, and ninja. Which class is better for nukes or is there another better class than this? Thnx guys
