The location looks fine too me, I'm just worried that we can't play near the path because of pedestrians and what will the owners of the houses think of us yelling and shooting eachother in their backyards?
There is no "ultimate" gun in my opinion. The two you listed are pretty equal in preformance. All guns have there strengths and weaknesses. Everyone also have there own playing styles and preferences, this is one of the reasons why we don't allow these threads.
