I ran into this dilemma when using 74LS76's and 74LS76A's for a student lab. The TI datasheet is at:

This chip comes in two versions, master-slave (74LS76), and negative edge triggered 74LS76A). The description at the beginning tells you that when the clock is high, J.K inputs are loaded into the master. On the high-low transition the outputs are transferred to the slave. The end result is that your data must be stable for while the clock is high (master-slave version), whereas it must be stable for one "setup time" (20ns for 74LS76A) before the negative clock transition. Most people would want the edge triggered version, keeping inputs stable while clock is high (master-slave) would be more of a pain.
