My experience with having an East German and a Russian for a year and firing about 1500 rounds thru each is that they are both the same accuracy wise and ultra dependable.
The overall finish on the E.G. is nicer and it feels "softer" in your hands, the Russian has a hard sharp edged feeling. Trigger was slightly smoother for the German.
I found the sights on the Russian easier to see but watch that rear sight screw, mine just flew off one day and I never found it, a common problem. A pistolsmith was able to adapt a High Standard screw which actually worked better than the original!
If you are thinking concealed carry, the Russian's rear sight will definitely be a snag problem, go with a German or Bulgarian.
