Not all of the functionality that Qlikview offers has been implemented in Qlik Sense yet. But with each new release more functionality is added. Meanwhile you can use extensions that have been developed to add missing functionality. Have a look at branch.qlik.com and use its search functionality to find out if there already is an extension for what you need.
Qlik Sense Enterprise does support Section Access, which is not implemented in Qlik Sense Desktop. Other than that I think an app will work the same in both (disregarding multi-user enterprise features).
Qlik Sense (all versions) do not have alot of the functionality that you have in QlikView. QlikView is a much more mature product and also is not intended for self-service like Qlik Sense is.
Over time we will see more functionality. But they are not ever likely to be the same between the 2 products.
