Viltrox af 33mm f 1 4 vs meike 33mm f 1 4 stm?

On the specs this site lists, these two are close to twins. Both are 33mm f/1.4 primes for APS-C, both autofocus, neither is stabilised, and both come in Sony E, Fujifilm X and Nikon Z mounts. Both frame like a 50mm on full frame, with f/1.4 giving about the depth of field of f/2.1 on APS-C. The camera lists are the same too.

The site doesn't cover price or optical differences, so I can't call a winner from it. Compare current prices for your mount, then check the third-party lenses notes to confirm your body supports the autofocus features you want.

Look at the Viltrox AF 33mm f/1.4 and the Meike 33mm f/1.4 STM pages for the full details.
