Beretta 92FS Inox or 92SB?

[Yournamehere]

Alright I've decided to try and trade in my S&W 5906 for a new pistol, mainly a Beretta 92 series. A pawn shop down the street that my friend got his gun from has had a Beretta 92FS Inox. However, last week I saw a very rare Beretta 92SB pistol in very good condition at a gun show. Here's the info on both guns:

Beretta 92FS Inox (Stainless version):
American made
Tritium Night Sight (rear only)
Hogue panel grips (no finger grooves)
1 Mec-Gar aftermarket magazine
Old style blue Beretta factory case
90% Condition or better, $550


Beretta 92SB:
Italian made
All original parts including grips
Not sure on magazines or case, didn't have it out at the gun show
90% Condition or better, $530

Bear in mind I have a S&W 5906 with 3 mags and case for trade in value, and won't be paying for the gun in whole. I'm also not gonna take this gun into combat where "the stainless finish will glare" or "the slide will break and fly back in my face". I'd just like some advice on each ones value as a gun and as a collectible, and yeah I guess overall reliability (one was made a few years ago and the other in the 80s when the slide cracking thing was an issue, but I don't know if that will affect the gun as I'm not testing it as a military testing group would). Any intelligible input is greatly appreciated.
