Webfont performance - webfontloader vs preload

I am currently thinking about using webfonts from Google, but I have still no idea which way to do it, because there are many different opinions on the internet.

I have following options:

• Webfontloader by typekit and google
• rel attribute preload

When checking the performance of both on a slow 3G network, I get similar results regarding the performance. The downside of the webfontloader is the FOUT (Flash of unstyled text). Is there a way to get around that? The downside of preload is that its not supported by many browsers. Is there a fallback? I couldn't find one. Maybe you have another entirely different way.

Thanks for your help,
