I think Tumi, Rimowa, and Samsonite are all mission specific.

I have a preference for tumi cabin luggage, the dividers are bit more sustainable, and sturdy, east to pack suits and compartmentalize your essentials easily. , I use the TegraLite products from tumi,and have both the cabin luggage, and carry on. The only downside is that the weight of the bag itself is substantially more. My tumi on a recent trip to dubai got some heavy damage(bent inward, and a half broken wheel.) I went the tumi route to get it fixed, but it was too much work. Then I remembered I purchased it at Nordstrom, and took it right back to them, and they replaced it with a new one,(I didn't have the proof or purchase, but I had purchased it with my nordstrom card, so they were able too look it up.)

I like Rimowa, because, they're stylish, lightweight, and durable. I have the I like it, but they are scratched easily, but very very durable. I use my rimowa when I travel between Europe, North America, and Australia. I find it in most instances (operative word) the baggage handles are a bit more gentler.

I have samsonite luggage for cruises and travel to asia. They are light, durability is okay, and for the price I may good value for money (i get mine from macys and there are always offers.) I have had a samsonite on a trip to india sustain damage, and the airline reimbursed me to replace it.

It is what you value, whether is price, or lifestyle; and for me its specific needs to my trips.
