#1
Best for a featherweight FPS mouse with precise tracking, long battery life, and deep tuning. Skip it if you need lots of buttons, top-side DPI switching, or Armoury Crate-free simplicity.
Pros: weight, grip texture
Cons: software usability, profile switching
#2
Best for deep customization, strong battery life, smooth glide, and a fast sensor. Skip it if you need lightweight FPS reliability, clean software, easy side buttons, or a natural-feeling joystick.
Pros: glide smoothness, scroll wheel quality
Cons: analog joystick usability, shape comfort
