what changer should be used on NetBSD ???

[cngo]

Hi, 
 
Can anyone advise what changer I should use with amanda on NetBSD. I've tried 
chg-chio and chg-scsi ang both work fine on NetBSD. But I don't know if those 
changers have any advantages or disadvantages when they are used on NetBSD. 
Kindly give me your comment. 
 
Thank you,
