Voigtl nder apo ultron 90mm f 2 vs ttartisan 90mm f 1 25?

Both are manual-focus 90mm primes for full frame, so the choice comes down to mount and aperture.

The TTArtisan 90mm f/1.25 is the one I'd usually point people to. It's f/1.2, which gives more light and a shallower background, and it's made for Sony E, Nikon Z, Canon RF, L-Mount and Leica M. On an APS-C body it frames like 135mm.

The Voigtländer APO-Ultron 90mm f/2 only fits Leica M bodies, such as the Leica M10 or the Leica M11. If you already shoot M, it's a sensible, smaller-aperture option. If you don't, the TTArtisan is the better buy.
