Pick the Sigma 24mm f/2 if you need a wider field of view and slightly brighter aperture for low-light or shallow depth-of-field work. The Sony FE 50mm f/2.5 G stays the better choice if you prefer a standard focal length, marginally lower cost, or prioritize a more compact design. Decide based on whether 24mm or 50mm better suits your shooting style.
