I've never fired the HP. I didn't like the ergonomics when I held one (I was interested in purchasing it at one time). It's a really slim gun, reminded me of the 1911 ergonomics, something I don't care for either.
I've got squishy hands, so I like rounded fat grips, which is why I went with a Beretta M92FS (I got mine 489.00 used)
The Beretta is an amazing piece of work. The most accurate handgun out of everything I've shot before (1911, Sig's, XD, Glock). It's a bit heavy though, but if you're not using this as a carry weapon, then it shouldn't be a problem.
My vote goes for Beretta. but like I said, I never fired the HP, so I can't pass too much judgement. I would go with whatever feels better in your hands, but just so you know, the Beretta is a reliable, accurate and well machined pistol. Combat proven too.
