Apart from the aesthetics, What are the actual main differences between these mice ?

I currently have the ROG Spatha which I am enjoying immensely but would like to add other ROG mice to my arsenal 😄

One of the main things I love about the Spatha is that it does not use that soft rubber coating on the body or the left/right click or anywhere else for that matter, Would the Pugio or Gladius also not have this rubber coating ?
