All three. Lol.
I bought the azur first because I felt the braided handle and light canvas was "oh so summer!" I adore my azur artsy and she has aged beautifully. I loved her sooooo much that I bought the infini artsy in empriente. Worth. Every. Penny. Such a beautiful and well made bag. Having 7 pockets inside is a dream. However.....the mono kept calling my name. I had bag envy every time I saw someone's mono artsy. I tried to convince myself that my mono speedy, delightful, and mono neverfull were enough and it would be repetitive. That didn't work LOL. I compromised and didn't buy a third new artsy, I found a beautiful pre loved one on Yoogi's and saved a good amount of money! AND I don't have to break in that handle again
would I trade my azur artsy for mono? No. I love them both. My advice...get whichever steals your heart...or all of them!!
