Qlik Catalog Help

Hello Gents

I have some questions according qlik catalog that i can not find an answer of it

1- can i make preparation and transformations on data that is registered or addressed not managed?

2- which one is better in performance to load data and make some transformations using prepare in qlik catalog or to load data and make transformations using load script in qlik sense

3- which is better in performance to make three multi tiers architecture like (first tier to connect to data sources and convert tables to qvd then second tier to load qvd to make some transformations and third tier to load multiple transformed qvds to make some associations and then visualizations) or to use qlik catalog to connect to data sources and use prepare tab to add some transformations and then publish to qlik sense ?

and by default when to use each scenario?
