the evo has the newer sensor model which is alsoed used by the razer deathadder 3.5g and the logitech g400 so i would take that one but there is not much difference both work flawless.
Now you are wondering why the razer sensor is called S3888 and the logitech one S3095. Both have special licenses with the manufacturer so no one else can buy their model off. But overall they are pretty much the same as the normal one A3090. And yes there are differences. they use another lens other led's and other switches and so on. But the laser itself is pretty much the same as i heard. Pretty much all the other parts of their mice is different
