Main difference is not robustness. It's that CD are digital and can be copied perfectly.

CD-R, and especially CD-RW variants, are not robust, and not a good archival form. CDs themselves are pretty good.

Vinyl, with some care for environment, is really good for archival.

Amazon will also automatically add (most?) vinyl purchases to your Amazon Music Library, and allow download.

The Amazon downloads seem to all be 44.1 khz mp3 (just downloaded an album of mine to check).
