IMO, Bootstrap v4 is much stronger than Foundation for many reasons. Here's one... b4 has a much stronger "foundation." What do I mean by that? Well to be honest if you actually look at the HTML structure of both frameworks, you'll see that b4 is not only utilizing more modern techniques but that they have reduced and simplified their markup. ie, navigation items. b4 uses <div>'s for each nav element which allows for more control while foundation is using an older technique of unordered list items. This is just one example of how b4 takes a more wholistic approach to every aspect of their framework. I don't fault foundation at all and it probably has to due with the talent of the core b4 team as well as the massive community that they have, but I can't see a use case where I'd choose foundation over b4.
