7artisans af 10mm f 2 5 vs samyang af 14mm f 2 8?

Both are full-frame autofocus primes with no stabilisation, so the choice comes down to field of view and mount. The 7Artisans AF 10mm f/2.5 is the wider and brighter of the two, and it fits Sony E, Nikon Z and L-Mount. I'd pick it for interiors, architecture and big landscapes. It pairs well with a Sony a7 III or a Nikon Z6 II.

The Samyang AF 14mm f/2.8 is the less extreme choice, with a slower aperture, and it comes in Sony E or Canon RF. If you shoot a Canon EOS R6, it's the one that fits. Not sure what the f-number means for your shooting? The aperture section of the lenses guide explains it.
