are you talking about pros and cons after you finish study? well if you are going to do PHD ,do in anyone of them you mention, if you love research thats good, well after finishing , you can either be researcher and teach or can work in industry, reasearch is intersting thing where you will learn lots of new things,every experiment will make you think lot,you can design your own research,but i don't feel like writing grants every year and worry about grants every year if i were to become professor , that's me but i don't know about you, some people do enjoy writing grants and doing reasearch..the best thing is after finishing study just shoot for industry.....
