Best modern ambidextrous mouse

I've been using the Razer Viper Ultimate for the past 4 years, its an ambidextrous mouse with side buttons on both sides. I've gotten used to this and frequently use the extra side buttons in essentially every game I play. Obviously, 4 years of almost daily usage of a peripheral means its wearing down and I've been looking for an alternative. Something new, light, and with the side buttons. Wired or wireless doesn't really matter to me, I'm just looking for an upgrade. Any help would be much appreciated!
