Strong Bags, hands down for me. I have used mine for seven years and have yet to replace a part. Everything is replaceable on it, even the skin. So in theory you should never have to replace the bag, just individual components. The telescopic handle is pretty durable and rigid, and if it does break, I think it's only $25 for a new one. Everything on this bag is replaceable. I've used this bag in every type of environment from regional, corporate, and fractional. Ive had 7 days worth of cap packed in it. The skin can be taken off and washed when it gets dirty, there is no paint to scuff down to the metal, or sharp edges to cut yourself on, and the frame is metal. When I got mine it came with a duffle for free that is still in use today as well (still looks brand new). I just recently got the crew cooler to go along with it, and is equally as well made. I lookforward to many years out of it as well.
