In my opinion, there is no comparison between the two. I've carried the Beretta for the last five years as a duty weapon in two combat zones. I would gladly exchange it for a Hi Power, 1911, or better yet...anything SIG.
Our Special Forces guys, to including any Navy Seals they were working with, usually carried either HKs or Sigs. You'd occasionally see some top notch 1911 .45s...but you'd never see a Beretta among them for a reason.
The Beretta is seen a lot in Hollywood (think lethal weapon) and is a familiar platform for many. For those of us who are forced to use it outside a range environment, you probably won't find nearly as many fans of the system. The action get fouled very quickly due to its design, and when it does, the gun turns to crap.
Keep in mind, all of the above is a personal opinion. If your life experiences differ from mine, you may end up loving the gun. If you are looking for a weapon you can enjoy at the range and for CHL, then it may work for you. My very first handgun I ever purchased was a 9mm Brigadier, and I sold it almost immediately after finding a NIB FN HP.
