Grabit IMO is the best for NZB's as it is VERY user friendly and as long as you are only using NZB's it never has problems. Where as if you were to download articles in certain groups that contain more than million articles there tends to be problems.
NewsLeecher on the other hand has the ability to moderate how many articles are downloaded, so it eliminates this problem, but this program has been know to be buggy, and "
lose" the articles that were downloaded... You make your opinion, but these are the two most used...
