JP Beast Wars Second (1998)

There aren't too many Beast Wars Comics, but if you have read some, let us know about them... or have a refresher read and post up some comments or reviews.

Are any worth buying?

Are there any specific issues or stories you'd recommend to others?

How do they compare to the current era of Transformers comics... and do you think they should revisit this era as a comic?
