Well, I also voted to stay on fast ring. But not out of fun or satisfaction but desperation. By time WP8.1 is (even more) retarded and limited compared to the other two mainstream mobile OS. So if you wanna catch up even a little you "have to" enroll in fast ring.
Bottom line of all those threads about how the latest build is doing for you then can often be summarized as: "running pretty well, smooth...." followed by: "but... except....although...hardreset... roll back..." and so on.
I not use me WP as daily driver anymore but follow the latest news and always install the latest build. But I not see a bright future...
