For a first Start I would suggest to read the Blog Entry from Henric Cronström to understand the differences.
There is no comparsion list of QlikView and QlikSense as both are different Products. Often you just have to do it in a different way in Sense than you did it in QlikView or create an extension or wait for the function.
The Pricing is for both Desktop Versions free, but with Sense you can more easil share your application. From FAQ:
Can I share apps created in Qlik Sense Desktop?
Yes. There are no limitations in sharing applications between different installations/instances of Qlik Sense Desktop.
Note: QVF files need to be located in a specific folder - C:\Users\USERNAME\Documents\Qlik\Sense\Apps
The folder cannot be a shared drive folder or a shared folder. Once a qvf is open, it is modified so other instances of the Desktop cannot open it or copy it.
Also there will be a Cloud Function later this year, sta tuned for details.
