Pick the Samyang AF 50mm f/1.4 FE II if you prioritize a brighter f/1.4 aperture for low-light performance and shallower depth of field. Choose the Sony FE 40mm f/2.5 G if you prefer a slightly wider 40mm focal length and a more compact, lightweight design. The Samyang remains the stronger option for bokeh and light sensitivity, while the Sony suits those valuing versatility and portability at the same price.
