What is the best if any architecture/cad programs that can be exported/imported into blender?

Wondering if there are any good programs where it is easier more efficient to model a house in then export it into blender? I am looking to make house modeling easier.

Sketchup is probably the most user-friendly. Blender itself is great too. Autocad and Archicad are ubiquitous. Revit is for bigger projects I think. Rhino and especially the Grasshopper plugin is pretty unique for parametric design (fancy modern buildings).

Surely Sketchup, the ease of use and the speed of learning / work is absolutely unique
