It depends on what you are asking honestly. With work you often have a somewhat set schedule and amount of hours (ignore overtime and manipulative asshole bosses for now), outside of those hours, you are essentially free to do as you please.
With studying its kind of the same thing except that you have multiple assignments, assessments and exams with a clock ticking down to their deadline. So unless you like getting bad grades, resitting exams or even kicked out, you are best hitting the books or getting those assignments finished.
If you were wanting what I think is objectively better with the exact same amount of time in each (say 35 hours of work vs 35 hours of study). I honestly can't give an answer since I have never got a job yet so I can't give a personal opinion (just give those points though the work one could be wrong depending on certain occupations).
