I've been using Pro v19, having also upgraded via a copy bought at the ME show a few years back. My problem isn't that great results aren't possible - clearly, they are - but that I personally find it very difficult to use in 3D. Where in Fusion 360 I can just click on the face of an object to set the drawing plane, I have struggled to do the equivalent with TCAD. Add in parametric and history features, plus the fact (for me as a hobby user) F360 is free, and my personal decision was easy. But it may just be that I have completely missed something fundamental that would have allowed me to make progress with TurboCAD.

I think that we are living through interesting times where the guys originally responsible for Solidworks have brought out OnShape, Autodesk have brought out Fusion 360, and both are likely to change the cost and availability model of these kinds of tools over time. Commercial users may see things differently - while the licences are expensive, powerful tools that do everything and are fully supported mean more productivity, maybe - but as a home user, I'm happy to grab what I can while it lasts!
