I consider Brazil to be way stronger than Arabia for a CV due to the ability to convert GAP into tourism. The thing about this mechanic is that the GAP pool isn't fully depleted when a golden age starts, it only loses the amount needed, with the rest carrying over for the next GA. Once you get permanent golden ages, you can store large amounts of GAP that keep carrying over to the next, making them count twice, thrice and so on as the exceeding GAP carries over. With proper use of great artists, you can gain massive gold and tourism bombs every 20 or so turns.
Due to the above mechanic, I also find Brazil to benefit way more from Tradition for the GAP upon great person birth and the synergy with Artistry, than from Progress and Authority. These two can't maintain permanent golden ages nearly as well, and end not carrying over that much GAP when they get a GA chain. There were old patches in which Progress could compete with Tradition, but nowadays, I find Tradition way stronger for this civ.
