Why would people goto Nvidia Omniverse over using UE5

Hello, Just wondering what your thoughts are on why someone would convert to Nvidia Omniverse over doing it all with unreal…or would you UE5 in tandam with Omniverse?

Omniverse is aimed more at archviz
it has some useful tools like “audio 2 face”
I don’t think it can replace UE
and it only works with rtx
