Is the 6.2 a better engine than a 6.0

[6.2]

I would say go with the 08. I just got an 09 and LOVE it!! I never drove one with the 6.0 but the 6.2 is a great engine. I had the same engine and tranny combo in my 07 Sierra Denali and it feels so much better in the H2 than it did in the pickup. I had the shifting issues in my Denali but I don't have them in my H2. I also like the interior of the 08-09s much better than the previous models. Either way you really can't go wrong though.

The 07 shown is a lifted Hummer, would you also be looking at getting a lift on the 08? If so you might want to ask the question about how the 6 speed tranny has been handling a 6inch lift with larger tires. I'm not sure that this has been really tested enough to give you a good answer.
