Budget 0-20k Glorious Model D or Razer Mamba Elite - Suggestions

[NoMansLand]

I am looking for a gaming mouse.. mainly for FPS gaming.. and software-controlled RGB is a must-have.
Have finalized these 2.. does anyone has any experience with either or both of them? What are your suggestions?

Model D is better.
