I've looked at the documentation for both but haven't used them for client prototypes so far so YMMV.
FramerJS is a javascript framework and the documentation is good. If you are comfortable with JS then you should be able to dive in and make some headway.
Alternatively, Quartz composer is a whole new beast–the recent demos I looked at are confusing. I honestly have no idea how all the boxes and lines interact to build a demo.
