I have haven't used ProConect.  I use ProSeries.  But it will be a cold day is you-know-where before I would change software to another Intuit software.  Intuit is evil and doesn't give a *blank* about tax professionals or Intuit's professional tax programs.

You said you want the "ability to clearly view the data input on the forms themselves", which means I think forms-based software is what you are looking for.  Beside ProSeries, both ATX and TaxAct Professional have similar forms-based entry.
