After years as architects we’ve settled on AutoCAD LT and Sketchup as our complimentary tools of choice. SU lets us quickly give clients the eye candy they need, ACLT lets us utilize the years of experience we’ve already invested in the platform without the considerable expense of paying for Autodesk Building Suite.
We tinkered around with Revit but the learning curve was more than it was worth to us for the $5m and under projects we do.
In the end, whatever works for you, works for you!
