I have worked extensively with SS on multiple projects and from a designer/user input level it's pretty amazing. It's easy to use, the output is fantastic and to your point, displays very well on mobile. You have to determine what it is you're trying to do as your end-game. If you want to aggregate images/content that links off to clients manually then SS can get that done - it's not overly time consuming and IMHO based off of the fact that you're just learning WP, it'll be the best display output you could ask for.

A big part of this is determining how you plan to set up your affiliate site - - are you a blog, a guide, a comparison tool, etc. because depending on what route you take, you'll see that SS has some limitations. SS does a good job of optimizing their webpages for search, which is a huge benefit if you don't have extensive SEO/SEM/Coding knowledge.

Just my two cents.
