PUC vs UFRJ

Hello everyone, I’m currently a Master’s student studying Energy Science in the Netherlands, and next year I want to do my master’s thesis abroad in Rio de Janeiro. Right now I’ve spoken with professors from both PUC-Rio and UFRJ (COPPE specifically) and I have the option to do my thesis at one of them. I’m trying to decide which one is better overall — not only academically but also in terms of lifestyle, vibe, and the type of people who go there. Thanks alot
