It's a shame that you can no longer get the most advanced sensor/tech on a simple mouse without stomaching the annoyance of 12+ buttons and an awfull shape/theme.
I think Zowie is a great example of a company that, for the most part, has the best optical sensors on the market(made better with a custom lense), with fairly simple plug-and-play mice. Just don't get the Mico whatever you do, the buttons are so stiff and the scroll wheel is terrible, it'd be my favorite by far though if it had the same sensor as either the EC1/EC2 or AM, the same scroll wheel, and the switches of the AM.
The EC switches are feather light, I like switches a bit on the stiffer side to prevent accidental clicks and the AM is good for that. The small size and light weight in combination with the small feet of the Mico feels amazing on the Zowie G-TF Speed mousepad, the larger feet feel a bit rougher and more frictiony but still good. Having tried all three the AM seems like the best balance to me. People often point out prediction as a deal breaker, but almost all mice(including most gaming mice) have some amount of it and people probably don't know. Some of it is a good thing, but the word prediction tends to raise a red-flag to gamers.
