I am using G300 logitech, after using it I certainly can say they truly are worth every penny I spent on them. death adder is really good
u can change arctosa to logitech G105
u should ask it urself, what u can hold good in your hands. i havent seen rat 3 it seems to be little bigger. moreover I prefer symmetric design. so u should ask yourself about what will be fine in your hands. deat adder is safer choice
