Such great choices! here are my thoughts:
PM - I have the regular mono and LOVE it. Love love love it. It's light, can fit a surprising amount (to me anyway) and is so compact and soft and I barely knew I had it on. LOVE it. I am concerned about the glazing issues but since I bought it directly from LV, I have faith that they will take care of any issues if they arise.
NeoNoe- I had this in noir and just returned it to LV this week
It was an impulse purchase and when I took it back out to try on and possibly wear, it just didn't wow me anymore. As others have mentioned, it's a bit bulky because of the square structured bottom. It's light and fit a lot which are huge pluses. I loved the inside divider, adjustable strap, and cinch top. But it can't compare to the PM for me.
Artsy - I have never owned one but the complaints of the uncomfortable strap keep me away. It's a beautiful bag and I know many on here love it for many reasons!
Out of those 3, I'd pick the PM reverse, no question but that is only my opinion. Once you get to LV and try them on, I bet there will be one that just screams your name! Can't wait to find out what you get!
