Nikon 24mm f/1.7 and Sigma 30mm f/1.4

Hi, I am looking to assemble a prime lens kit for my Z fc. I don't mind all DX lenses so I am looking at options for a normal lens. I already have the Sigma 56mm f/1.4 and I like it a lot. I narrowed my options to the Nikon 24mm f/1.7 and Sigma 30mm f/1.4. I know there are trade-offs in size and weight but what would optically be the better lens? Do you have experience with it?
