I got myself a new mouse, G502 Logitech, so nice. My last mouse lasted for 5 year almost.
I hate the look of those gaming mouses, and extra buttons bug me.
I've stuck to the budget Microsoft mouse basically forever. They only last me a year or two before I wear out the scroll wheel and buttons, but I love the size and feel of them, and they're so cheap I don't mind replacing them so often.
All personal preference obviously. A mouse is all about comfort, and I know a lot of people like the extra buttons for gaming etc.
