I haven't used CMP (Assuming you mean cam model protection) but what I can say is DO NOT go with the company DMCA512. The guy running it basically flaked on multiple models using every excuse possible not to get the work down that he promised (In the hospital, family died, dog died, computer hacked, changed owners etc).The owner also called me on my phone and acted very odd/creepy including saying my body looked fertile and kept pressuring me to hook up and get into mainstream porn with dogfart company. I only used DMCA512 for one month and it was a disaster.
I currently use model-launch and am very happy with their services
