All of them are excellent fields to go into - congratulations on choosing a health and wellness career. The demand for these rarely declines. In fact, BLS.gov says that massage therapy careers are projected to grow faster than other occupations easily through 2016 if not longer.
I would say "massage therapy" is what the common public tends to look for more, so the quantity of clients you get may be higher when you start your career. However, "reflexology" is more of a high-end specialty area, so while fewer clients may seek you out, you may be able to make more money per client.
There are tons of benefits to a massage therapy career, such as the independence of flexible hours and scheduling, being lucrative and making good money, the constantly growing job demand in the field, you get to help people with a very valuable health and wellness service, and going to massage school and getting licensed is typically very fast and affordable.
