Christoph,
There is a good comparative treatment of those models in Duffie and
Beckman's _Solar Engineering of Thermal Processes_ (chapter 2). My
understanding is that the Reindl model is adapted best for south facing
tilted surfaces (ie solar collectors) and that the Perez model is
adapted for more general surfaces (building facades). There are a few
different Perez models (updates that I am not sure are treated in the
Duffie and Beckman book)
Best,
David
