Having owned both bags, I would definitely choose the disco over the pochette metis. While LV is definitely my fave luxury handbag brand, the disco is one of the best small crossbody bags ever made, imho. The disco and the PM fit roughly the same amount of items due to the difference in their shape (boxy vs. wide and flat) and interior organization. Even thought the PM is larger than the disco, the PM's divided interior compartments actually reduce the amount of useable interior space. The disco is extremely durable with no major manufacturing defects (unlike the PM, which has a well-known glazing problem). While I really like the look of the PM, the disco is equally beautiful imho, and it is, overall, a better value and a more versatile bag (both in terms of transitioning easily from day to night, and in terms of working with a variety of outfits).
