Time for a new suitcase?

My Rimowa suitcase, basically an older version of the Essential Cabin model, experienced a bit of an issue during my return from London and the seam around part of the zipper gave out. I have taken it to a repair shop but they seemed pessimistic about being able to fully repair the break. The Rimowa had a good 11-year run. As such, I have started the search for a replacement.

I tend to prefer the clamshell style suitcases where when opened, there are two sides where items can be stored and not just a lid opening into a single storage area. My preference comes from having the ability to separate my clothes out so if I have a long connection somewhere (like Singapore on a recent San Francisco-Singapore-Bangalore trip) I can have items readily available rather than digging through the entire suitcase. I do like Rimowa and with their recent change to include a lifetime guarantee for all suitcases purchased after July 25, 2022, they are an even more compelling option. However, I am open to suggestions; So here’s a quick list of things I am looking for:

  1. Four-wheel spinner. It’s nice to have a suitcase I can walk beside or manipulate in tight spaces.
  2. Nice wheels. High quality wheels that are smooth and don’t need to be replaced often.
  3. Clamshell design, for reasons stated earlier.
  4. Quality. I know there are cheap suitcases out there, but I’d rather have one for a long time.
  5. I lean toward hard-sided suitcases, but I’m open to soft-sided as well.

So, what recommendations do you have? Anything I should definitely avoid?
