Anyone went from Razer Deathadder V3 to Viper V3 Pro?

[THE LORD]

What's the difference between the two? And which is better?

I have the deathadder V3 wired and it's the perfect shape and feel for me. Wondering if the viper would better.

I wanted to get DA v3 but when I looked at it and noticed it's a 5-button mouse I said hell no.
I will get another v2 at this point.
My current DA v2 is dying. The rubber skin is peeling off and the side buttons are dying. They are not optical and are rated for way fewer clicks than the main optical ones which are rated for about 70 million clicks.

I really need those additional 2 buttons. DA v2 is a 7-button mouse, while V3 has only 5 buttons.

If they put 7 buttons into v4 then I will get it.
