As the breeds origins are Chow, Samoyed and Wolf Spitz/Keeshond and the breed is fairly new, then you will get dogs with tendencies more to one of the founding breeds than the others.
Samoyeds and Keeshond temperaments are what you really want, but they are the noisier input, and the chows are your more taciturn. Chow temperaments can be not as pleasant.
So you can get the odd iffier Eurasier and some noisier.
I would have had one had they been in the UK when I lost my Belgian Shepherd in 1992, but went for the Elkhound, which has been established here since 1870's, a bit smaller, not as hairy, but only in wolf grey.
There is an event coming up shortly called Spitz in the Park, well worth attending as somewhere to see all the Spitz breeds
