I can't get excited about one freewheel over another. To me, they all work OK. Some care about tooth pattern for shifting, and that seems like the most important difference.

As for reliabilitty, I've had good service from some of the cheapest freewheels. Yeah, they fall apart sometimes, but not often, so it's hard to predict which model is the most prone to that.

Noise is a factor, but it doesn't really matter that much to me. If I'm coasting slowly near a pedestrian, I kind of like the freewheeling noise being a gentle alert system.
