Sigma 24mm f 3 5 dg contemporary vs sony fe 24mm f 2 8 g?

Both are 24mm primes for full frame, both autofocus, and neither has stabilisation. The main differences are aperture and size. The Sony FE 24mm f/2.8 G is a third of a stop brighter than the Sigma's f/3.5, which helps in dim rooms and gives a little more background blur.

The Sigma 24mm f/3.5 DG Contemporary is the one I'd pick if you want something small enough to carry everywhere. It also fits L-Mount cameras, which the Sony doesn't.

If you shoot Sony E and low light matters more than size, go with the Sony FE 24mm f/2.8 G. For a sense of how focal length and aperture change the look, the focal length converter is a handy place to start.
