As a non-designer that's not really an issue for me. There are so many cheap or FOSS design templates, snippets, icons, etc available these days that it's not a huge problem to put together a package of them for Foundation. I use Bootstrap when 1. the default Bootstrap theme or a third party theme are sufficient 2. I don't need Foundation's better grid system 3. I'm using something other than Ruby (which for me is most of the time) Foundation for: 1. There's a specific problem that their better grid system solves. I haven't come across this yet, but am aware of it for when/if I do. 2. Client wants a highly customized Ruby-based site with no hint of the Bootstrap look As someone mentioned above, you can use Foundation and borrow design and/or javascript elements from Bootstrap and elsewhere if you need to go that route.
