Yes, was attracted to this theme primarily due the multiple configuration homepage options that existed within the 'live preview' – however, unlike many previously purchased templates, these configurations aren't 'available' to just plug-in inside the dashboard/backend. So, the question:
For the image grid(s) that exists in the live demo, which 'page builder' tool is used to create those image grid elements?
You can use visual composer page builder with block elements. It is very simple to use.
It is example tutorial for http://themeforest.nomadtheme.com/supermag/home-page-1/.
Step 1. Please create a page with Page Builder + Blog + Pagination Template
Step 2. Please Configure with Page Options
Step 3. Set Loop Page Options
Step 4 Add Visual Composer Elements
Step 5. Add 12 columns row and fullwidth blog elements
Should looks like this
Step 6. Add 4 Columns row
Step 7: Add 12 columns row and Block L19 Element like step 5.
Publish your page.
