and there is one thing i dont got a ide on
wich of em should i use to texture my models in
thanx and best regard the danish new

Silo is a great modeler, and if you have the pro version also has very good UV tools for creating maps.
I would say, model in Silo for base mesh, and high res mesh, do the unwrapping and export the whole enchilada to different apps for actual painting etc.
Take your finished model into Houdini to do everything else.
