I have owned both (in fact, I just recently sold my Beretta). They are both grreat guns. The Taurus started as a licensed copy of the early Beretta 92. Over the years, it has evolved in a slightly different direction. Some parts still interchange.
The Beretta is considered "finer", with somewhat better machining, fitting and finish. In my opinion, it is no more reliable or durable than the Taurus pistol.
I let my Beretta go because I like the Taurus safety better.
Of course, you mentioned the PT99! If you want adjustable sights, there's no comparison, since the Beretta 92 has fixed sights.
