I'm also really loving Gucci right now too and have gotten 3 bags in a month!
I love both style bags and probably would say to get both but in different colors. If you can only choose one right now I would opt for the flap bag because it could be dressed up and down.
Oh that's awesome!! What bags & colours did you get if you don't mind me asking? If I got the flap in nude what other colour would you suggest I get in the camera bag? It's so hard to decide!! Thanks for your tips
