Despithe my mother language being Dutch (Flemish), I normally use the English version but had a look at Nederlands and Nederlands 2 and altough I see some differences in word usage, I feel like both are very acceptable.
Some translations are "better" in Nederlands, for others I'd prefer the Nederlands 2 version.
I'ts also a matter of personal preferences.
An example: In lower right corner one can select Slide or Timeline view. Here I prefer Dialijst, it's more descriptive than Dialijn.
In general if I would use the Dutch layout, I'd go for Nederlands and not for Nederlands 2.
