I do not own vrayPattern, but I do own ForestPro and it is the same story as Cscatter.
Even if you decide to scatter your geometry and allign it to surface normall you still won't get continuous mesh if the base mesh you are scattering on is not dense enough.
Even if it was that would be super cumbersome to setup each time. Not even close to that geopattern aproach.
I'm not a coder and dont know the code behind it, but to me it is clear that scattering solutions are a totaly different pair of shoes than this Geothing and can't be compared.
Possibilities are endless with this thing. Imagine scattering tiny pieces of bark on your tree trunks etc.

But I believe that thanks to this kind of plugins full switch to GPU is within reach soon, even for people working on really large and demanding archviz scenes :)
