I prefer the German side because I am more familiar with, and impressed by, the engineering side of it. Meaning their firearms designs.
However, it seems that there are plenty of "Germany ONLY" players and that side is constantly having many more players join it. This pisses me off, and I make a point of it to go to the Soviet side and try to put those "I join Germany even when that team has 33% more players than the Soviet side. Screw balance and all that" in their place. Almost always the DP-28 for me, and more and more the Mosin-Nagant.
