CNA/MA? Which is better?

Hello all.

I am a pre-nursing student. I have been looking for a CNA training progam close to my area without much luck. I did find a MA program at Platt in Dallas but I do not know much about being an MA. I have learned a tons reading the CNA rants and I was hoping someone out there could tell me the difference between a CNA and a MA. Can you gain much patient care experience as an MA? Is it worth it?

Thanks!
