Hi Joss,
I think that where massage is concerned, it's very much 'different strokes for different folks'. It depends what you need, what your expectations are, etc. Massage (a.k.a. Swedish Massage) is the base qualification for most other forms of massage. You can't do Aromatherapy without first having completed this course, for instance.
The benefit of Aromatherapy is the use of oils, which can help ina variety of ways, as essential oils penetrate the bloodstream and has an almost medicinal effect. For instance, if you have trouble sleeping, a massage will help, but a massage with lavender oil is a surefire way of ensuring a good night's sleep.
Swedish massage can be performed with oil, cream or talc (basically, any substance that ensures little friction between the therapist's hands and the client's skin). So if you wanted a massage during your lunch hour, Aromatherapy might not be the best option, unless you want to go back to the office smelling of oils and clinging to your clothes.
Hope that helps!
