Question Mixing logic families


Is it advisable to interface LS family digital logic parts with a uC like AT89C52 or PIC, or should I use HC parts instead ?

For example, would it be a good idea to connect a 74LS74 to the above mentioned uC pins or would it be better to connect a 74HC74 ?

An anecdotes and ideas/suggestions ?
