Could also be a quality control thing -- ya never know. Like Chessparov said, it's supposed to be more of a flattering vocal mic, so it's going to have some sibilance issues on some people. It's going to be more of a hit-or-miss kind of thing, but when it hits it really hits.
The 4050 has been a studio staple for many years now, and has appeared on a ton of records. It's a safer choice in comparison, and though it might not sound like magic on a lot of voices, it will never sound bad. And tracks recorded with it are easily manipulated with EQ in order to sound magical after tracked, because everything is basically "there" and represented so well.
On the right source, the T-3 can have a "big-money" high end to it, while the Audio Technica mics tend to have big-money midrange. If you could only have one mic in your collection, the 4050 would be the best and safest choice. If you already have a large collection and need something kinda' special to round it out, then the T-3 would be a good choice.
That's my take on it at least.
