What do you guys think is the best area to be employed in? Depending on various degree levels, which area is better for undergraduates, graduates, or those who already obtained a degree? Which area is more helpful for getting into graduate school (if you're an undergrad) and which area has more opportunities for advancement? Is there any difference in treatment or the type of work done? I ask because I have a choice between continuing research in my current lab at my university as an undergrad or becoming an intern at a national lab, but I also think this thread would be beneficial to many people.
