I have been going at this for almost month about the razer deathadder or the Logitech g502 proteus spectrum. I'm currently have a g502 proteus spectrum and it's a pretty good mouse. The grip is really good and I like the feature of changing your DPI while gaming. Although I've heard a or of thing about the razer deathadder chroma. A lot of esports players use it and my favourite player of all time. Shadowburn. Uses this mouse. I'm currently playing overwatch and I do sometimes play some cs:go but mainly overwatch. Please help
