I have no regrets with my Rimowa Original Cabin Twist. It's functional, attractive and when I took it in to complain about it squeaking I got a new set of wheels which fixed the squeaking within 10 minutes. Yes, there are a lot of people you wouldn't want to necessarily be associated with carrying similar bags, but if you've chosen to live in Dubai you're going to be used to associating with awful people anyways.
If you want to be different, you could consider one of the special editions: The Hammerschlag is gorgeous if you can get your hands on one, and the Aime Leon Dore collab suggests they're going to keep pumping out limited edition colours for a bit.
