I've ridden a couple of years on the Shimano SPD's and a couple of years on the Speed Plays, but only about 6 months on the Keo's.
Shimano SPD:
Pros: Inexpensive
Cons: Single-side entry, pressure distribution across the bottom of the foot is narrow and caused hot spots for me
Speed Play:
Pros: Double-sided entry, great ground clearance when cornering, adjustable float
Cons: Bulky cleat system, difficult to replace cleat screws, periodic lubing required with grease gun. Requires a wrench for installation/removal vs. an allen wrench, and believe me, they can occassionally be a pain to remove.
Look Keo:
Pros: Simple cleat system, broad distribution of pressure across the foot
Cons: float is implemented though the cleat system: Silver cleats = 4.5% rotational float while Red cleats = 9.0% rotational float.
