Hi folks, I too recently had to choose a boat.
Looked for a raft for my wife and I. Owning a PVC Ducky from Aire I looked at the Puma first. Bladders inside welded PVC are very stiff and rugged. I've no experience with non-bladder PVC boats.
In the end I went with a 10.5 Outfitter from Hyside. Mostly because of weight and pack-ability. Also, as much as I LOVE my Aire ducky (Super Lynx) it traps silt and junk and needs detailed cleaning to stay nice. The Hyside is just a hose off job. The Hyside is Hypalon with Urethane fabric added on the bottom.
The center is black urethane and the side tubes have blue color matching urethane coated fabric layers applied. Gives me a comfy feeling when I hear it slide over rocks in the river.
Hyside got a bad rep when they created their cut rate line called "Rio Bravo". Those boats were built by a Chinese company and never delivered good quality. Those boats are no longer sold by Hyside. But that Chinese company is producing boats and may be found imported by others.

The boat I have is excellent quality and I expect it will serve me well for many years. This is a link to the South Korean company that makes the CSM rubber and the boats for Hyside.
This company does a great deal of government and military production btw.
As for glue vs. welding. CSM does not weld.
In the end, you mostly get what you pay for. And materials aside, quality is what's important.
Keep all boats coated with 303 protector and they'll all last a long time.
