It's not worth it for most, myself included I used to travel extensively. At least weekly domestically and once a month overseas.

I've worn out backpacks and shoulder bags. Never a rolling carry on or suitcase.

Do they break? Yes, eventually. When they do have the airline pay for em. If your traveling enough to wear out or break a bag. You have status with the airlines. It's never taken me more than 20 minutes to get a brand new bag and be in my way.
