Viper v2 pro or v3 pro se

Hello, I currently have been using a viper ultimate gen 1 I got in January of 2021, I’ve been using it and love it, recently I’ve had to replace the top part of the shell, and it has become very sensitive, clicking the back of the mouse actives the triggers and as well if I press the mouse as a whole a little the bottom shell trigger the click, I have the options of either getting a v2 pro or v3 se, I don’t mind either shape, the v2 pro is 73 dollars and the se is 99, I have to wait longer for the v2 as it comes from outside my country, while I have next day shipping for the v3 se, before shapes I don’t think there is big difference between, I’m guessing it just comes down to shape? Thanks
