All of the engines are good, if they were maintained.
The early Gen IV engines(07-09) with active fuel management have lifter issues. I would stay away from those.
The later Gen IV engines have VVT, some people hate it. I've never had an issue.

That's the interesting thing about the way GM mixed up the chassis and year splits. I was looking at the fact that the 6.2 was available in the 06 Denali and Escalade SUVs. The year split fooled me... The SUV or at least some of them were already GMT900 chassis in 06...
I don't have lifter issues on my LS4 5.3L in the Impala but that would weight things toward the 6.0L even further as long as you can get a lower mile example.
If you're going to re-work the engine anyway then the possibly dodgy AFM lifters make less than zero difference.
