Hummm that's a tough choice!
depends on your needs really, they are both REALLY spacious bags. I really like the azur, it looks really tasty(it reminds me of white chocolate) but i would have to say go with the monorgueil, I just think that the Monogram is the best line from LV I love the vachetta with the dark brown background.
Hope this helps! And good luck the hardest thing to do is CHOOSE.
