When it comes to extra components and JS extensions, Bootstrap and Foundation are basically head-to-head.

But here are a few extras that Foundation has that Bootstrap does not.

Form validation, Abide: HTML5 form validation library
Off-canvas menus: Easily place your site navigation off to the side of your site
Pricing tables: Ready-to-go table, designed to show prices for a subscription based product
Responsive media, Interchange: Website loads different media for different devices/screen sizes, so you can customize the user experience
Right-to-left support: Modify the text direction; great for sites in other languages where characters move from right to left
Tour, aka Joyride: Give users a tour when they come to your site
