In most cases, salary is no the most important thing, particularly at junior positions.
What should ask yourself is what your goals are, both medium and long term. Based on that, you can choose.
A priori and without knowing anything else, I would say that PG´s name has a lot of advantages: brand, the know-how you will learn in a well-functioning company, network, exist opportunities... But again, most important thing is to see what aligns best with your goals.
Hope it helps!
