Tax pros are like developers, most comfortable closer to the bare metal if you will. They use a separate product line that mimics the actual forms closely. They don't like the interview style because it just slows them down when they're barreling through hundreds of returns. Beyond the UI, there's no difference in the calculations they work with so that should tell you something.

Maybe (someday) you can build two different UIs to the same return. For example, I can hire a CPA and then share with him/her my return. I can upload the docs and numbers, and the CPA can do the magic using the bare metal UI.

I heard from my CPA that Intuit provides very poor support for their ProSeries / Lacerte software, because they are trying to get everyone to use Turbotax instead. So even CPAs have a pain point that you could solve.
