Dermatology is one of the most misunderstood specialties, given that physicians learn almost zero derm in their training. There is no free lunch. If you honestly think you can make good $ while being lazy/unproductive, you are misled.
Also, the concept of "number 1" you pose here is silly; there's no such thing. Attendings in many fields have a similar lifestyles to Derm, even in some fields you would not think possible (e.g. surgical fields). Decide if you like the field first, but only do so after spending ample time on service. Without that, you won't truly understand what being a resident/attending in a field is like and you will end up spewing the same old tired generalizations around that each field has.
If interested in really understanding Derm, i'd recommend a full months rotation at an academic institution and research together. Try to get enough clinical experiences in all subspecialty areas if possible (i.e. get enough dermpath, mohs surgery/reconstruction/procedural, medical derm (blistering, CTCL, rheum, autoimmune, infectious, etc), inpatient, and pediatric if possible). Make sure you also attend resident education and try to read through a few chapters of a derm text (like Fitzpatrick) to get a sense of the detail and if you like it. this will allow to you decide if you are interested, after seeing all the pieces at hand.
