I have both bags and honestly, I find them very different. The marmont is a bit dressier but that is what I love about it. It easily transitions to a bag I can wear a bit more dressy and looks sharper with a date night look. I had the soho disco in red and never grabbed for it. As much as I love a red bag on others and really wanted one in my collection, in the month I owned it, I never grabbed for it once- It felt much too bold for my comfort level. I sold it and bought the black and have absolutely no regrets. They are both fabulous bags and staples in my collection- get both! You will use them!
