Logitech all the way.
Currently using the G500s. 2 Years of zero problems. Easy macro recording. Will detect installed games automatically, however I run a custom macro pack for BF4. DPI up to 8200. Palm or Claw grip possible/suitable. Weight adjustable, I prefer very light.
3 Months for me to upgrade to the G502.
Listen to advise relating to wired and wireless mice. Stay away from wireless if you are a FPS gamer.
Prior to this I had the RAT7. pretty damn nice, just a bit to heavy.
Other than that, it's up to your budget.
G502 is a stunning mouse the Cougar 700M for performance and looks... about R50 over budget...
