Display content to end users depending on group

Hi,

What is the best way to display text or content depending on what group an end user is part of? 

When a logged in user visits a page, I want to display some text in case they are part of one group, and some other text if they belong to the other group.

I have tried to look at examples about visitor groups, but they usually base the displaying of content on things like location or time of day while I want to go to the backend and check what group the logged in user is part of, and based on that display the right content.

Are visitor groups the way to go or is there some other solution I can read up on?

Thanks!
