Rimowa FTW.
Well actually it just depends on what you want. I wanted something that can take my suits, shoes, modicum of random stuff (including diving equipment) and my straight razor (the reason I have to check luggage). I looked at every brand out there, but just came down to realizing all I needed was a box to put stuff in that would be:
A: Closed
B: Locked (tsa)
C: Light
D: Ugly as sin so I could find it easily

Every brand out there I looked at with internal compartments just showed how cheap their construction was. Total crap in ever line below B+R. Seriously utter crap, worse than men's warehouse crap.
In the end Rimowa offers the salsa, it is perfect. No interior crap to deal with, the hold down straps are made of a proper material and the attachment points are METAL, oh my. Not cheap plastic that slides with more than 2in/lbs of pressure. The only problem I have with it no suit compartment, but so far packing well has my suits coming out fine.
My one piece of rimowa luggage has made tons of international flights and domestic. So far I have had no issues with it. I would show a picture, but my girlfriend, who has her own luggage btw, took it on her trip. She is awesome at packing "small" so she can fit more in that one suitcase than I can somehow, but because the darn thing only weighs 7.5 lbs, that 70lb international weight limit isn't even close.
So why did I go with rimowa over halliburton? Simple, the metal cases are awesome on both sides. Seriously killer stuff, but they are HEAVY for either company. I am not transporting anything that needs that kind of protection. If for some reason I decide to buy something that needs protection, then it is time to find the local fedex/ups and ship whatever it is home. Real insurance and considering the cost of the metal cases... The non metal cases on the other hand just don't feel the same. Rimowa has testing done by all kinds of groups and all the reviews I have seen show it as being heads and shoulders above the rest, including halliburton. I found a dealer about 2 miles from my house.
Sorry the extra 800-900 dollar just isn't worth it for the metal ones IMO.
BTW, the prices you see on rimowa are MAP. Dicker and bargain with the dealer and you can get a better price, fairly significant amounts off are normal. I promised I wouldn't give out what I paid for my stuff but if you want to know who I used, let me know though local dealers are probably the best way to go.
Yes, the deal was better than the deals offered by the "factory seconds" dealer and mine was dropshipped directly from the factory. Brand spanking new.
Do I sound like a shill yet or am I still in the range of "I just had my coffee this morning and really like my luggage"?

(no, i'm not a shill for the luggage or the local dealer. Though I did just get some sartorio suits through ebay. woo!)
