It really depends on your modeling mind frame and what you think needs to be modeled and how - a REALLY loaded question.
Free form modeling - Joint Push pull is great for odd geometry or especially thinking in section (as opposed to thinking in plan)
Massive 2D plan import via DWG, maybe Faceup.
I’ve used Profile Builder too, especially if you think that way.
Stick by Stick construction - Medeek Wall is great if you want to get BIM like stuff out of your model.
FlexTools is great for putting openings into walls quickly, if that’s a critical issue.
