Lily definitely for me, it's such a classic, simplistic lines, easy to open and has got everything going for it.
I have the LV Alma in the next size up, PM but it's quite difficult to get into because of the shape & zip. It would drive me nuts struggling to access anything smaller. Mine is in the Vernis leather and the Epi is even thicker and stiffer.
I have one Gucci, the soho but none of the others have ever appealed. The one you have mentioned looks eminently forgeable.
