I totally agree that we "should be better focused on helping to improve ALL of them! PTC, SW, Autodesk, etc." However, from my experience, PTC has it's doors closed tight to accepting user input and improvement ideas. There isn't a way to help improve it. If you can show us the contact, how they listen, and how they implement those changes, please do! SolidWorks is very focused on listening to user input and regularly makes improvements based on user ideas and suggestions.
For my biggest example of needed improvement, the measure command in PTC is killing me! It's years behind compared to SolidWorks, and years is a long time in today's tech. There are so many steps required in PTC. And in SolidWorks, you don't even have to use the measure command, it will show auto measurements in realtime.
