I personally prefer Icon+Text over Text-only. And icon-only is often confusing on websites/apps - it only works if one uses the website/app regularly like the Office <=2003 toolbar. Also the recent trend for black and white icons makes them sometimes harder to understand. Colorful icons worked fine, in older Office <=2010 and elsewhere. Though finding a good icon set with 500+ generic icons that fits one needs means taking compromisses.
