Kit@18mm 1/160 f/5.6:

100% center crop

Sigma, same exposure:

100% center crop

Hmm, my hands didn't shake much and I aimed straight for a snow-covered groove at the center of the center crops (center of the tree's...base..stem..what's it called?). It should be contrasty enough to focus on, and the kit does it.

Same scene,
Kit@18mm, 1/100, f/8, 100% center crop:

Sigma@18mm, 1/160, f/8, 100% center crop:

The Sigma looks worse at 18mm still, sharpness-wise.
I don't know exactly why exposure and white balance seems a bit different with the same parameters; though that was Auto for WB and maybe exposure compensation happens by default in manual mode.

Sorry. I wasn't being sarcastic. The shots using the Sigma were clearly better, at least to me, and the shots using the Sony kit didn't seem to get much better as you stopped it down.
