how good is the razer viper v4 pro?

i currently have the viper v2 pro and have had it for some years now and have always liked it alot but ofc since ive had it for years the sensor can be annoying sometimes, the battery life has gotten a lot worse, and naturally having the same mouse for years i want something new. i use a claw grip with a little bit of my right side of my palm on the mouse and the viper v2 pro feels great to me so id figure id stay comfortable with razer. most likely going to upgrade to the v4 pro eventually, but also want to get some experiences with it.
