unipolar is easyer as 4 transistors to ground are needed.
Bipolar needs 4 more to V+

Unipolors are easy to drive and have less torque

while bipolors are bit harder to drive and give good torque and speed.

Try google you will find lot more information about them.

come up with specific questions which will be easier to answer
