For the RHS $0$ case, they are automatically equivalent under the normal definitions of viscosity solution (touch by any smooth function for top, one having nonzero gradient for bottom): if you touch from one side by a smooth function, the two inequalities are equivalent for smooth functions; this is clear if the gradient is nonzero, while if it is zero the top one is vacuous while the bottom one isn't checked. With a nonzero RHS, they are just two different PDE, the difference has nothing to do with viscosity solutions per se.
