The big guy is finally arrived!!
Again: is my first proper mouse, so I can't say anything from an expert standpoint, but it feels amazing!!
I immediately changed the grip from fingertip to palm without great pain (it must be said tho, that I claw the mouse at work, so I'm not that picky with the grip), and it's super comfy and buttery smooth.
Especially loving the wheel, after so many years of a sort-of broken one, that recognized a scroll-step every 4-5.
Now I feel I could even install CS:GO again, without the fear of being embarrassed by teammates spectating me and seeing my old sensor going crazy and jumping the view to the sky spinning super fast.
