Don't know if you are talking about webfonts or fonts you are just using locally in Photoshop. Here's my take on webfonts: About a year ago I started using typekit with a 50 USD plan for a 3 of the sites I maintain/run. Recently I switched one of the sites to googlefonts. Googlefonts has less choice of fonts. But I did it for two reasons. I can download the fonts and use them offline - also in Photoshop Design mockups. The fonts are served faster, especially for sites targeted for europe.
