The Compact Jazz Collection- Yea or Nay

To those that see this-

I came across an add for “CD’s for sale” and the person is selling a bunch of jazz titles at a reasonable price. I don’t have many jazz titles so I thought it might present an opportunity to experience something different. 
This batch for sale includes all of the “Compact Jazz” releases except those that were of various artists (about 77 disks).

Question- Were these disks done well? Production quality, transfer and the like? I usually stay away from “greatest hits” style of releases so I was hoping someone may have experience with these that can comment.

 Thanks!
