PNT bags are TANKS. They are heavy and they are expensive, but you cannot go wrong with one. Mine is over 1.5 years old and looks brand-new other than a couple dents and paint on the skidplate.

I'm sure BR bags are very nice but looking at their website I question how well they would hold up long-term to the rigors of airline work, especially if you commute and have your bag thrown in the back of an RJ a couple times a week.
