Discussion B & Riley vs TravelPro: Which is the Better Carry-On?

Earlier posted about a $2150 carry-on bag that generated some interesting responses. In considering more practical options, I'm now torn between B & Riley and TravelPro. Both brands seem to have a solid reputation, but I'm curious about real-world experiences. Has anyone used both? How do they compare in terms of durability, weight, and ease of use? Especially interested in feedback from frequent travelers who've put these bags through the wringer.
