i used to lean toward samsonite because of design and features, but i've consistently had issues with the zipper tags, which break off, and the telescoping handles, whose locking mechanism wears down. the warranty means nothing to me because the contracted repair stores have no sense of urgency, as if the samsonite tickets go low on the list of priorities. when i was coming to china, i waited as long as month for a handle part, the bag was less than a year old, and samsonite could've solved it by simply sending me a new bag. they refused. i had to buy a cheapo duffel bag from costco because i wasn't sure the repair would be finished in time. the repair shop finished fixing my bag literally a day before i flew to shanghai.
i don't know who "owns" travelpro, but i'd go with those bags if you want longevity. for anything small, like laptop bags/rolling carry-ons/overnighters, look at solo. i don't know who those people are, either, but their bags have been superior (in my experience) and for an unbelievably low price.
if you're in the states and have time for shipping, go to ebags.com. you can't beat their prices, the detailed user reviews are especially helpful and they usually ship quickly; or they'll email you if there will be a delay.
