I don't know what these weird grouping are, but 8VM/SCORE easily wins.
Obviously the first grouping is out. OIALT was clearly his worst era vocally, being the soonest after the injury.
SFAM/LSFNY era was ok, but he's improved a lot since.
SDOIT/ToT/LaB was a bit inconsistent, but improving a lot live, and in the studio SDOIT was one of his best.
Octavarium/Score was his best tour vocally since the injury. Just amazing.
SC/CiM was pretty good, although unfortunately CiM doesn't reflect that at all.
He's been great on the BCASL era, but he didn't have a chance to record a live DVD for scrutiny, so I can't vote for that, and I'm not sure I can choose anything over SCORE.
