FPS: 360 claimed I really liked the ASG Bersa BP9CC when I review it because it was such a well rounded gun in a very compact and well built design. The Umarex Walther PPS perhaps exceeds the Bersa BP9CC since it is even more compact, seems to have a bit more blowback recoil while still retaining decent fps and accuracy, and the Umarex PPS has a superior design when it comes to the built in allen key for tightening the CO2. You even get all of this for less cost then the ASG BErsa BP9CC. Don't get me wrong, I would not be without either gun, but if I could only have one it would be the Umarex Walther PPS.
