To give you a bit of context, the _large_ majority of people buy the advanced package (which really surprised me). The advanced package really just tries to bring all of your new knowledge together, going over d3 + React and d3 + Angular. It also has detailed walkthroughs of 3 complex data vizes, which could be really helpful. But both versions give you a great foundation to build off of.
