I used Travel Pro after I switched to flying charter, where I know the bag smashers (AKA me) are going to be nice to the luggage. When I flew airlines I used Luggage Works, the big honking heavy steel framed ones, I flew Dash's and it survived multiple crushings, falls, beer spills (didn't happen to me but a captain I was paired with once.)
If it's not going to get thrown around much I 'd say save your money and get the Travel Pro one. The luggage Works are nice but about 3x more expensive.
