I have owned both, and traded both away so I don't have an ax to grind or sell.
I found the PT92 every bit as good and as reliable as the Beretta and being a couple of hundreds of dollars cheaper it is a far better value.
Here's what Wikipedia says

In case you're wondering why I traded them away is because I found that getting to the extractor and the firing pin to clean it was very difficult. I'm a little OCD and I learned in the Army (pre-Beretta days) that a gun is not clean until you clean the firing pin and the extractor.
