Only the London and Decca recordings of the Stones US and UK releases were remastered. So, Sticky Fingers and Exile on Main Street, as well as your second group of recordings (which are currently on Virgin Records) were not re-issued.
As for Beggar's Banquet and Let It Bleed, if you can still get your hands on the 2002 re-masters (gatefold hybrid SACDs) by all means do so. The sound is the closest to the original vinyl of any CD version that I have heard.
Check out this Audiogon thread from 2003 for a discussion about these remasters.
