Sigma 20mm f 1 4 dg hsm art vs sigma 20mm f 1 4 dg dn art?

Both lenses are 20mm f/1.4 autofocus primes for full frame, and both frame and stop down the same way. The difference is mounts. The Sigma 20mm f/1.4 DG HSM Art covers Canon EF, Nikon F, Sony E and L-Mount. The Sigma 20mm f/1.4 DG DN Art covers only Sony E and L-Mount.

So if you shoot Canon or Nikon, the HSM is your only choice here. If you shoot Sony E or L-Mount, both fit, and I wouldn't pay extra just for the newer name. Pick whichever you can get at a good price. Neither is stabilised, so this is a lens for light and subject, not for shooting handheld in the dark.
