You could always use a data-url SVG in the CSS file for the "best of both worlds"... and a compiler could make this a pretty painless process... but a single sprite sheet for your entire site is probably worth the extra request in most cases, since you could lazily load your icons and speed up your initial page render, rather than waiting for the CSS to fully load to display content.
