Do you recommend using border-box or content-box?

and is one better for a responsive web design?

Content Box is by-default the value for initial boxes(elements) on the page. We use Border-box so that we can have same width and height and width of boxes despite the change in padding and margins. Mostly, we use Border-box when we reset the whole page. It's only matter of need, if you need content box we use that, if we need border box we use that.

It depends on what you are doing.

If you're primarily concerned with content dimensions, the default value of content-box is fine. But when your concern is exterior dimensions, it may be more convenient to use border-box instead.

Good designs can be created by proper applications of either setting.
