RD/MS/MPH/PhD

Hi, everyone! Although it is not an early time, I still can't decide to apply MS or PhD program. I never consider myself as such kind of guy to stay in universities or institutes, and I want to meet more people. But now I find myself more familiar with the tubes and pipette in the lab. Besides, as far as I know, MS programs are less competitive in good universities than PhD ones. Is there anyone who could help give some suggestions on which one to choose and tell me something about the career choice? Thank you~~
