Another vote for Zero. IMHO anyone who buys this thinking "nice and shiny" is fooling themselves as that won't last it's first trip. Having gone through various types of cases over the year there is nothing that matches the confidence of having your stuff in a Zero case. It's the 'fud' as it comes down the baggage shoot and hits the carousel that always brings a glint to my eye
I've also got Tumi carryon and have mixed feelings. It's very good luggage, highly practicle and the two pieces I have are sized perfectly for the overheads and underseat but it hasn;t been as rugged as I thought it would. Definatly showing it's age.
