Hello!

It can not be termed as "MS is a higher level course than MD". Both are postgraduation degrees with their own specializations. Their are differences between them, such as MS is a PG Degree in general surgery where as MD is a PG degree in general medicine. Both can be pursued after MBBS. The level of both the courses aren't different but MS is for some fields where more of surgical expertise and the skills are required. MD is non surgical but there are some branches where surgery can be a part of MD.

It is sometimes said that MS degree is slightly superior than MD, it is because the person who completes the MS becomes surgeon while the one completes MD becomes a physician. A physician cannot be a surgeon, the surgeon can work in place of a physician with more study of medicine. The surgeon can earn a lot more money than a physician, if he or she is good and skilled. Both the fields have good future prospects.
