Background: I own neither, have handled, fired, and sold both. I am not a fan of Taurus or Beretta, though I appreciate Beretta quality.
I am of the opinion that the PT92 is the best Taurus on the market, and I prefer it to the 92FS. The Beretta does have better fit and finish, but it doesn't translate to much actual difference in use. They both tend to run well, are easy to shoot accurately, and gobble up recoil. I haaaaaaate the 92fs safety (and own a PX4 with it), and find the PT92 safety a considerable improvement.
Because of my personal preferences, I wouldn't buy either. I only use my PX4 for dry fire, and will probably dump it. I like Sig far better for DA/SA.
Currently Own: Beretta PX4 9mm, Glock 23 (Gen 4), Glock 19 (Gen 4) x2
