I would say get both maybe. Why maybe you ask? As stated the 101 is in 40, if you do not already have a 40 in your collection, that means stocking up on another caliber of ammunition, and 40 is more expensive. If getting the Beretta 92, then you're still using 9mm ammo so no need to re-stock anything.
Like you said, the Beretta is more sought after, however saying that it is BETTER than the Taurus will have a tendency to evoke flame wars (very passionate feelings toward one gun or another).
I only own Taurus'. One 92, and one 100. However I did find that on gunbroker I could get a 92 or 99 slide and right on the 100 it goes. That's how I usually keep it anyhow.
In addition to that for EITHER the Taurus or Beretta, you can get a 22 conversion slide and now with the same grips and frame you can pop off 22lr all day on the cheap.
If I had to make a choice between the two, I'd get the Beretta, as you would use the same 9mm ammo. If you have another 40 gun then it's a tossup. Get both they seem to be asking a reasonable amount, go out and shoot them and sell the one you like less.
