Brazilian expats I need your help

Good evening everyone I hope to find someone who's gonna answer my query. I'm about to initiate my visa application and I was wondering if I should apply with or without the Carta de convite. I have a friend who's going to invite me and I'll be staying at their place. Of course the decision completely rests on the embassy but I'd like to know which approach would be better. Hoping to hear from someone soon. I thank you in advance
