In my experience, A&B undoubtedly tries very hard to put out quality suits. It is really the logistical problem of fit and alterations that made me reconsider after my first suit. The material was very nice, and the workmanship was on par with some Hong Kong stuff I've seen with interesting details like gripper waistband strips, cuff guards on the inside of trousers and decent (if not carefully considered) buttons.
Unfortunately, if you tend to be someone who notices small gaps at the neck and slight bunching behind the shoulders and other problems that would be less obvious to an alterations tailor the experience could be rather frustrating. I could never get it to fit just right so I eventually gave up and donated it to goodwill.
Since that experience, I've become a regular client of Ned's (and Len Logsdail, but that's irrelevant) and have purchased perhaps ten suits from Ned, each with distinct characteristics. Yes, there is less handwork and the linings are less shiny etc., but I really only care about the fit, silhouette and style (in that order) when getting a suit for less than $1000. For that, Ned is above reproach and would never want me to be seen in something that doesn't fit very well, even if sometimes my ridiculous requests (english-backed trousers) make him grumpy. With A&B, I never felt my salesperson had the eye for clothes necessary to make the fit perfect.
The A&B shirts, however were mild-to-moderate disasters with rather subpar fabrics and ludicrously stiff fused collars that bubbled and misbehaved in general.
Now, this was three years ago, so the company may have moved to address some or all of these issues, and I think for some people it might be possible to get your money's worth in an A&B suit, I've just found some excellent tailors who give me more than my money's worth.
