Ask HN: What's your favorite mouse

As a heavy workstation user I have typically gone with gamer mice like the Logitech g9 or g500 and now my g500 is failing. I've started looking around and see a lot of mice are hardcore gamer which now come with a lot more functions than needed. I've always been partial to gamer mice for their durability, ergonomics and construction. Being curious, I started thinking about what hardcore workers actually prefer for mice. Would love to hear.
