I have never had a problem with UPS. USPS constantly reroutes, and screws up the destination. To be honest, the issue with USPS is the distribution centers 98% of the time. As far as relative costs, 4x4 boxes are cheaper than the triangles or round tubes. Use pirate ship for UPS mailings, always cheaper. You can use a 4" diameter round tube and put it into a 4x4 square for extra protection. USPS was charging extra for the package length and that was one reason I stopped using them.
When I paid from my UPS account I found them constantly adding charges... 4x4 boxes were getting bumped to 5x5 and weights being adjusted. I haven't had that issue since Pirate ship.
