I really like the Time Ataks, the drawbacks being that the springs squeak a bit which can be annoying at first, they are a bit heavy and there is a tiny amount of rotating resistance but not enough to ever notice when pedalling. The float is excellent and you know when you are clipped in because there is a satisfying clunk and I have never pulled out of the clips involuntarily. I have Speedplay zeros on one of my geared bikes and they are great with the best float but have downsides: hard to tell if you are clipped in initially and the shoes need "cafe covers" to protect the plates even for short distances.
As for shoes, I think mountain bike shoes suit fixies best as you are tending to use a fixie for general purpose riding which involves more on and off the bike.
