Third-party Z-mount lenses

[8bit]

Just treated myself to a Z6 II - very impressed! Using my F-mount glass with the FTZ adapter just now but was looking at third-party Z-mount lens options and notice that Viltrox have 35mm and 85mm f/1.8 primes (amongst other things but those being the two primes I use most).

Has anyone got/played a bit with recent Viltrox lenses? They seem to get a good review against Nikon Z-mount equivalents considering the price, wondering if they're of a similar level as my Sigmas.
