If I were to be gifted one, I would take the trevi because it is so much more than the speedy cost wise. However, it would be the speedy that I would use more frequently hands down! I know, I'm no help!
if money isnt an issue, definitely the trevi pm! my sister has this bag and it looks absolutely gorgeous in real life! but then again, i'm dying for a speedy damier ebene because it is such a practical bag.
