I'm an Aire fan myself- I like the fact that they're made in the US, and I think the durability is pretty great for the price. The huge selling point is the 10 year warranty. Even if you rip a gaping hole in your boat based on your own bad driving, they will do the repair for free (you pay shipping). For Colorado boaters, I'm fairly sure that only means a trip to AAA Inflatable Repair (they perform work for Aire). I had a minor leak issue with a bladder recently- dropped it off on a Friday afternoon, and it was ready Monday. Cost: $0.
Some folks diss the bladder system because of the added weight, but there is no easier on-river repair for inflatables. Even relacing a busted valve is relatively easy to do in the field. I know PVC is known to degrade in heavy UV conditions, but I put a coat of 303 on the boat before it's out for the first spring trip. Maybe if I was leaving my boat in the sun all day all summer long, I'd be more concerned. My last set of Aire cat tubes were still in great shape 8 years after I bought them, and I did not baby those like I probably should have. I wanted to buy the raft that I'll be using for the next 20 years, so I bought the Aire 156. Had I not been an Aire loyalist to begin with, I would also consider a DRE boat- those guys are also local and super helpful....but only a 5 year warranty.
Now- as for performance, I'm probably not the best person to talk to because I haven't guided perfessionally and I haven't been able to try out a bunch of boats to see how each handles. Rafting always largely been a means of getting my beer, my dog, my kayak and my girl down the river.
