honestly it doesnt matter if it is 6400dpi or 10,000,000dpi. once you get to a certain dpi threshold you will not see any real improvment. i usually set my mice up at anywhere between 900-1500dpi, even if they are capable of 5x that number and i do fine. having too high of a dpi setting can pick up the micro twitches in your hand.
if i remember correctly the mamba is the wireless mouse razer makes. the deathadder is their basic corded model. for around $100 and $50 respectively both are way overpriced for what they are. with that said, the deathadder is functional and the build quality seems good enough to get at least a few years out of the mouse. the only issue i have is that the rubber surface is a dust magnet and can only be cleaned with water or other inert liquid.
honestly i dont mind the dpi, i does tweak the setting on my current mouse because all the time in game on desktop browsing i use almost the lowest or 2/10 of the setting.
what come up to my mine when questioning this is both of the mouse look almost different? does the size height are the same? how about the weight?
or if there actually something better out there for me?
i dont mind about the rubber on the mouse, my current mouse cover 1/2 of the surface with it, just that i hate when someone using my mouse with their wet or whatever it is.
i actually like how R.A.T. mice look like, but im really depressed by it build quality, is there anything similar?
i currently own a mouse from logitech g series, 2 years old though, i want a change of pace
