I've paddled with numerous Werners and AT's. They are both great paddles. From my experience they are both subject to occasional faulty layups which can result in a prematurely broken paddle. But both companie's customer service departments are greay. Every paddle I've ever broken (5 or 6) has been my fault, (hitting rocks, wedging, etc.) and AT and Werner have fixed or replaced all paddles in all instances free of charge. So I have a pretty hard time believeing negative reports about either company in that regard.
AT (the AT2 specifically) is the most precise, ergonomic feeling paddle I've ever used. Especially for playboating there is really nothing that I would rather have. My last AT2 lasted 6 years of pretty heavy use, including several seasons of nasty sharped rock CO creeking. The heavily ovalized grips make it really easy to tell exactly where the blades are in any situation, and the bouyant blades are the cat's pajamas. The blade edges are wrapped with dynel and do not wear down or decrease blade size. I lost my AT2 this past spring and will be replacing it in the near future. Especially for playboating, I've not used anything that could compare in terms of performance or feel.
I've had numerous Werner's and am currently paddling with a straight shaft double diamond (the foam core dynel edged blade). I've never been a fan of Werner's bent shaft feel, not quite indexed and shaped like what I'm used to, but I'm sure you can get used to anything. The glass and carbon non-foam cored blades do wear around the edges rather rapidly and decrease in size, but are a great deal price wise with some of the options you get with straight shaft, bent, etc. I have heard people say and do agree that for heavy creek boating use Werners are slightly stronger all around and more reliable paddles. That's why I have my current paddle, entirely for reliability's sake. But again with my luck with AT's I really have to room for complaint in that department.
And just for the record, I am not affiliated with any of these companies, just another joe.
Either way you're getting the best paddles available. Sorry about the long winded reply, but I've read a bunch of opinions on this matter, most of which lacking any real-life experience using both. have fun
