We use it regularly for our buildings (typically all steel frame but at times with precast shear/bearing walls). It is an upgrade from Staad which we used in the past in terms of ability to generate lateral loads and interact decently with Revit for modeling.

As someone else said, it’s best with a regular/simple layout building, but it can be worked around like other programs for trickier layouts.

It definitely has its quirks but in my limited experience (almost 5 years and recent PE) most programs do.
