Not always, there are a lot of limitations to models that you don't have with 3D models, name the support that limits how you can move a camera around the model. A 3D model, on the other hand, allows you to move a camera all round the model, 360 degrees in any direction. But at the end of the day, they're just tools and each has its own strengths and weaknesses and neither is inherently better or worse than the other.
