It is tricky. In essence general relativity does not require the existence of gravitons, curved spacetime is the origin of the gravitational force.
However particle physics tells us that all forces are carried by particles. So in order for gravity to work at a distance, logically it should have a
particle to carry the information.
Personally I tend to think of the curvature of space-time to be analgous to the graviton flux in space, thus they are equivalent.
