I was a confirmed fan of Delsey for many years but, in the last five, I have moved over to Samsonite. This is both for my largest, the mid-size and overnighter that is cabin legal even in Y and is also a roller.
The largest case is of a very light construction that appears too flimsy when open but has a clever interlocking lid and base that makes it very strong when closed.
Trying to find one case that meets all requirements (and is reasonably priced!) is very difficult. I have spent many hours working through luggage departments and finding nothing that suits.
