As a private practice cytopathologist, I see daily that one of the biggest deficiencies amongst my peers is cytopathology. I believe that having a good grasp of cytology not only makes you a better cytopathologist, but also a better surgical pathologist. Many pathologists are "architecturally handcuffed" meaning that most of their surgical diagnoses are predicated solely on architecture. If you don't believe me, pass around a tubular adenoma with a question of high grade dysplasia and see what sort of agreement you get. So, even if you hate the subspecialty, a solid handle on cytopathology will make you a better overall pathologist.
In terms of the attractiveness of the subspecialty, I think you have to like (or love) FNA. I operate an ultrasound guided FNA clinic in our practice. I like interacting with the patients and being able to render a diagnosis just by sticking a needle in it. Believe me, the patients like it too. They love getting a diagnosis immediately. Not having to wait a week to hear whether or not they have cancer makes a big psychological impact. US guided FNA still pays well too if you can do it yourself.
EUS-FNA of many lesions, particularly pancreas has become standard of care in many areas. Likewise for EBUS-FNA in the diagnosis and staging of many lung cancers. As an aside, I would take an EUS-FNA of a pancreas lesion over a CT guided core biopsy all day long.
In order to like and appreciate cytopathology you have to embrace the challenge of rendering a diagnosis using only a few cells and limited architecture (there is such a thing as cytoarchitecure). Cytopathology also allows you to directly interact with patients if you can learn to perform FNAs well. Fluid cytology can be tedious but so is looking at an entire tray of normal GI biopsies.
