thanks a lotG502 personally. While not AS ambidextrous like the Deathadder (even though it's technically meant to be right handed anyways and has a slight curve for it), it has more ergonomics and more grip IMO, it provides more macro keys, has weight control (135 to 170 grams). The G502 fits a large variety and range of hands because of its smaller slope compared to the Deathadder which is higher profile and is generally leaned towards bigger hands. While it's not as high in DPI, (12,000 for the G502 and 16,000 for the elite), the G502 is the first gaming mouse to have 12,000 DPI on a LASER sensor (optical for deathadder elite, but that's even more impressive since opticals generally have lower DPI than laser in the past, but not now...) although let's be honest, no one would actually use more than 10,000 DPI unless if you have a 1440 or 4k screen. However a big advantage laser mouse has over optical is that laser mouses can be used on basically all surfaces (including glossy ones) while optical prefers a mousepad of some sort. But it's still recommended to get a mouse pad anyways IMO, but the ability to use it on any surface can be a big plus especially if you travel alot or just move with your mouse.
That's all I can think of off the top of my head. Anyways, if you like a large hump on the top of your mouse and/or you have large hands, consider the deathadder. But generally I prefer (and many others) the G502 because of its features.

Too BIGsteelseries rival 300 for me all the way
