Well, they are as well made as anything on the market and Noel Buckley is a hugely talented engineer, certainly one of the very best in the bike industry. Get up close to those bikes and they are beautiful as well as tough as old boots.
That aeris is good value though, how much does is weigh and what shock does it come with? Be interesting to see how they hold up.
Edit: And, yes I really loved the look of the Knolly. Details are a lot more refined than they look from a distance. Although I have to say, I like their uncompromising appearance personally.
