If how a bow shoots and feels is a "performance issue", then I don't know of any bow that doesn't have "issues". I'm a little puzzled by the question.
I have a PSAV and, yes, I've had bows that are both less and more sensitive to shooting form errors. I'd highly recommend them to any intermediate to advanced archer; but a beginner might want to learn on a more forgiving style of bow. Personally, I find them to be a great compromise between speed and stability as well as about the most bulletproof bow out there.
I too have toured the Widow works and am also puzzled by your comment that the bows are not made by the same people. At least when I toured a few years ago, one person did all the layups, one did the tillering and another did the finish work. And yes, while a person lays up the riser, a machine cuts it; perfectly every time.
All that said, why not just take advantage of their "try before you buy" program? For a few bucks in shipping you'll have a definitive answer. I wouldn't worry about the difference between bows; I shot a BUNCH of then during the course of a 3 day seminar there and there wasn't a nickels difference between any of the PSA's that I shot.
