I really would much rather have a PT92 then a Beretta 92.
I voted for the Beretta only because it's the most accurate gun I have ever shot. If this is going to be a range gun, I would say Beretta. If this is going to serve multiple purposes (carry etc.), I say Glock.
EDIT: Make sure you shoot both. The Beretta's grip is fairly large. If you have small hands, you will not be able to get a proper grip.
I voted Glock because of primarily how if fits the hand and balances. Even though I have XXL hands , the M92 just doesn't feel right.
Yes , a well tuned M92 trigger is fine, plenty accurate, and as long as you realize a locking block is supposed to be a maintance item , very durable.
But the Glock fits me better , and fits a wider range of hand sizes.
