User content for different Groups

Hello

i have following issue:
i have a page called partners (Fachpartner)

if a user (should belong to a group =architects) is logged he has to see just limited Files to get access (no Pricelists)
If another User (should belong to a group =Partners) he must see also the pricelist and be able to download all the files

Whats your suggestion?

do 2 pages with different content one with pricelists and one without and have them redirected or or is it possible to hide specific content based on user Groups?

i have the plugin groups.. little complicated for me as beginner
i have the plugin profile Builder pro for registration

anybody got some ideas?
