This question distinguishes your experience and comfort level from your career goals and aspirations. If you are more experienced with one over the other and convey you'd like to keep it that way, the interviewer will assume you have no desire for growth, prefer the status quo, and rarely step outside of your comfort zone.

The best approach to answering this question is to offer what you are more experienced in. Then share your career goals and what you are aspiring to. If you are equally qualified to handle either, share your willingness to do whatever it takes to support the team and get the job done. Once you've ably communicated this, feel free to share your personal preferences quantified by your strengths. That will showcase you are flexible and willing to support the team and offers them an opportunity to ensure they provide you with greater job satisfaction.
