Tantalum capacitors are more sensitive to overvoltage conditions and can do 
much more evil things when misused (see Oldcrow's synth repair tips that 
were referenced here a little while back).

In some cases tantalum capacitors will be more desireable due to tighter 
tolerances and better high frequency response but it really depends on the 
circuit.  For critital power supply decoupling it might be better to use 
(for example) a 10 uF electrolytic with a 0.1 uF of a different type in 
parallel.
