Should I use SubD? Polysurface? Mesh?

So after trying my best in Revit, I gave up and installed Rhino after almost 10 years. So plz bear with me. I forgot all the differences between mesh, polysurface, and the new feature SubD. I need to create walls, that extrude from and Autocad file (in plan view). But as it extrude high and higher, it twists, rotate and curve around an imaginary dome. Please see the screenshots (the walls lines are in black color). Which approach is the best and more efficient way, which will allows me to modify the walls later? Something that gives me control points to select and rotate and move maybe!
