I used to have this version:

It had the original mono soundtracks and predates all the releases that started adding extra sound effects and cheap stereo effects. My brother had the Bosko versions on VHS and I recall it having better picture quality then those with a few scenes intact that were missing or altered due to extra fades and wipes added to the Bosko version. Beyond that I don't remember enough about the picture quality.
