Hero Banners & Live Text Q?

[BrunelOne]

Hey Guys N' Girls. What are the benefits of having live selectable text on your home page slider banners?

I understand that as live text Google can read the text, so there are keyword and relevancy benefits. But the question is how much impact on ranking this will have?

The reason I ask is our website solution can add live text but the fonts are limited to 9 basic fonts. We would like to use more jazzy fonts in the banner, but our only option then is to use a jpeg or png.

Thanks for your responses.
