In my opinion both are epic and well designed, but both have their negative sides. On Tactical the weapons seem to be unbalanced, some weapons are unneccesary to use due to the small amount of damage they make (Vector pistol, laser pistol etc.) or just because they are too slow to holster (MP5, TAR). The point is that players will never use these weapons unless they are new to Tactical and they are about to try out things that they have never seen at DX. Tnag doesn't have problems like this, I don't really see people using the same weapons during the whole game, but I don't enjoy using Tnag weapons as much as Tactical weapons... I prefer weapons that use our present or close future technology and this makes them more millitary-like if you know what I mean. Also most of the great Tnag weapons aren't even used on Altfire server which I think is not a very smart thing to do. (Minigun, Submachine Gun, Bio rifle etc.) Maybe if these weapons were present on all Tnag I wouldn't vote Tactical now
